Version Hipe Version Changes Full release notes
| PACS_CAL_78_0 | N/A | Since
  • Installed on Operational System since Jan-2017
Photometer
  • New columns were introduced in the aperture correction calibration file to account for the slight differences in PSF shapes depending on scan speed (20 or 60 ) and observing mode (prime or parallel). So far, aperture corrections were only provided for the 20/s prime mode observations but now the aperture correction task is able to choose aperture corrections most appropriate for the observations if the user provides two optional parameters paralellObservation (True/False) and scanSpeed (20 or 60).
| release note 78 | | PACS_CAL_77_0 | HIPE v14.2 | Since
  • Installed on Operational System since Jul-2016
Spectrometer
  • Updated spatial calibration of the spaxel sizes and layout at different chopper throw angles.
  • Update in the telescope background correction applied by the Pointing Offset Correction interactive pipeline scripts to reflect improvements in the beams regridding.
  • Updated RSRFR1 calibration file in the red leak (>190 um) that can be used with the interactive pipelines to flux calibrate the order 1 line fluxes within the leaked spectral range. This new version solves the cusps problems for some pixels.
| release note 77 | | PACS_CAL_72_0 | HIPE v14.0 | Since
  • Installed on Operational System since 10-Dec-2015

Spectrometer

  • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
  • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
  • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.
| release note 72 | | PACS_CAL_69_0 | HIPE v13.0 | Since
  • Installed on Operational System since 10th April 2015.

Photometer

  • no change

Spectrometer

  • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
  • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

| release note 69 | | PACS_CAL_65_0 | HIPE v12.0 | Since
  • Installed on Operational System since 19th March 2014.

Photometer

  • no change

Spectrometer

  • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

  • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

  • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    • New columns were introduced in the aperture correction calibration file to account for the slight differences in PSF shapes depending on scan speed (20 or 60 ) and observing mode (prime or parallel). So far, aperture corrections were only provided for the 20/s prime mode observations but now the aperture correction task is able to choose aperture corrections most appropriate for the observations if the user provides two optional parameters paralellObservation (True/False) and scanSpeed (20 or 60).

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    PACS_CAL_77_0 HIPE v14.2 Since
    • Installed on Operational System since TBC-Jul-2016
    Spectrometer
    • Updated spatial calibration of the spaxel sizes and layout at different chopper throw angles.
    • Update in the telescope background correction applied by the Pointing Offset Correction interactive pipeline scripts to reflect improvements in the beams regridding.
    • Updated RSRFR1 calibration file in the red leak (>190 um) that can be used with the interactive pipelines to flux calibrate the order 1 line fluxes within the leaked spectral range. This new version solves the cusps problems for some pixels.
    release note 77
    PACS_CAL_72_0 HIPE v14.0 Since
    • Installed on Operational System since 10-Dec-2015

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • no change

    Spectrometer

    • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

    Spectrometer

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total".

    Photometer
    • New columns were introduced in the aperture correction calibration file to account for the slight differences in PSF shapes depending on scan speed( 20 or 60 ) and observing mode (prime or parallel). So far, aperture corrections were only provided for the 20/s prime mode observations but now the aperture correction task is able to chose aperture corrections most appropriate for the observations if the user provides two optional parameters paralellObservation (True/False) and scanSpeed (20 or 60).

    • Installed on Operational System since Jan-2017
    Photometer
    • New columns were introduced in the aperture correction calibration file to account for the slight differences in PSF shapes depending on scan speed( 20 or 60 ) and observing mode (prime or parallel). So far, aperture corrections were only provided for the 20/s prime mode observations but now the aperture correction task is able to chose aperture corrections most appropriate for the observations if the user provides two optional parameters paralellObservation (True/False) and scanSpeed (20 or 60).
    | release note 78 | | PACS_CAL_77_0 | HIPE v14.2 | Since
    • Installed on Operational System since Jul-2016
    Spectrometer
    • Updated spatial calibration of the spaxel sizes and layout at different chopper throw angles.
    • Update in the telescope background correction applied by the Pointing Offset Correction interactive pipeline scripts to reflect improvements in the beams regridding.
    • Updated RSRFR1 calibration file in the red leak (>190 um) that can be used with the interactive pipelines to flux calibrate the order 1 line fluxes within the leaked spectral range. This new version solves the cusps problems for some pixels.
    | release note 77 | | PACS_CAL_72_0 | HIPE v14.0 | Since
    • Installed on Operational System since 10-Dec-2015

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    Spectrometer

    • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

    Spectrometer

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    • New columns were introduced in the aperture correction calibration file to account for the slight differences in PSF shapes depending on scan speed( 20 or 60 ) and observing mode (prime or parallel). So far, aperture corrections were only provided for the 20/s prime mode observations but now the aperture correction task is able to chose aperture corrections most appropriate for the observations if the user provides two optional parameters paralellObservation (True/False) and scanSpeed (20 or 60).

The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

    Spectrometer

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    Version Hipe Version Changes Full release notes
    PACS_CAL_77_0 HIPE v14.2 Since
    • Installed on Operational System since 29-Aug-2016

    *Spectrometer*

    • Updated spatial calibration of the spaxel sizes and layout at different chopper throw angles.
    • Update in the telescope background correction applied by the Pointing Offset Correction interactive pipeline scripts to reflect improvements in the beams regridding.
    • Updated RSRFR1 calibration file in the red leak (>190 um) that can be used with the interactive pipelines to flux calibrate the order 1 line fluxes within the leaked spectral range. This new version solves the cusps problems for some pixels.

    release note 77
    | PACS_CAL_72_0 | HIPE v14.0 | Since
    • Installed on Operational System since 10-Dec-2015

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • Installed on Operational System since 10th April 2015.

    Photometer

    • no change

    Spectrometer

    • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

    • Installed on Operational System since 19th March 2014.

    Photometer

    • no change

    Spectrometer

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    Spectrometer

    • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

    Spectrometer

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    • Installed on Operational System since XX-Dec-2015

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller.

    PACS_CAL_72_0 HIPE v14.0

    Since

    • Installed on Operational System since XX-Dec-2015

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • no change

    Spectrometer

    • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

    Photometer

    • no change

    Spectrometer

    • Update of the spectrometer calibration product: TelescopeBackground to version v8. The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    • Installed on Operational System since XX-Dec-2015

    Spectrometer

    • New spectrometer calibration product ExtendedSourceLoss. This calibration file accounts for the imperfect response profile of our spaxels in the case of extended sources.
    • Updates of spectrometer calibration products BeamsPerSpaxelB2A, BeamsPerSpaxelB2B, BeamsPerSpaxelB3A and BeamsPerSpaxelR1. The beams calibration files are now normalised such that the sum of the signal from all 25 spaxels is 1 when the simulated point source falls on the centre of the central spaxel.
    • Updates of spectrometer calibration products TelBackCorB2A, TelBackCorB2B, TelBackCorB3A and TelBackCorR1. In the Pointing Offset Correction interactive pipeline scripts we make an correction to the telescope background to get the optimal SED flux calibration, removing remaining "RSRF" features in the spectra not corrected yet by the telescope background model. These corrections are for all bands and are based on all Ceres SED scans on ODs 286, 485, 523, 782, 947, 1237, and 1420 and the corresponding version 2 models for Ceres provided by Thomas Mueller. The current update is a small correction to present calibration files to make sure the flux calibration is fully consistent with the telescope background model and pointing offset corrections as implemented in calTree version 71. The overall absolute flux calibration compared to the Ceres models is adjusted by 2 percent to be consistent with the PACS photometer flux calibration as is described in Mueller et al 2014, ExA. The proposed corrections are at the percent level. The biggest change is for the B3A SED observations as the current implemented corrections were not entirely consistent.

    • New version of the BeamsPerSpaxel calibration files. These files contain the beams which were published on the PACS Calibration WIKI in the file PCalSpectrometer_Beam_v5.tar.gz.
    • Provide fitted version of the Spectrometer BeamSize product. The calfile spectrometer.beamSize version 1 only contained a few measures. The resulting curve is not really smooth, and doesn't cover the whole wavelength range. A fitted version of those data is now provided, interpolated over all wavelengths between 50 & 220 um. A polynomial fit of order 2 does a good job.

The update consists in a correction of the absolute flux calibration scheme, now consistent with the same set of calibrators as used for the calibration block (excluding Uranus and Neptune). Additionally, this version has a better coverage of the wavelength range than the previous versions.

    • Changes for the spectrometer telescope background correction calfiles (PCalSpectrometer_TelBackCorB3A_FM, ...) related to the TelescopeBackground calfile version 8.

    • New version (v4) of the PointSourceLoss product with an update of "!fractionCentral_to_3x3" and "fraction3x3_to_total". These datasets contain the flux fraction of the central spaxel with respect to the central 3x3 spaxels and the flux fraction of the central 3x3 spatial pixels with respect to the total flux. The update takes into account an improvement of our knowledge of the PACS spectrometer beams, that was made possible by the improvement of the satellite pointing reconstruction. Additional measurements were also included in the derivation of these new correction curves, namely the 'fine rasters' (0.5 arcsec step) were used, along with the original ones (2.5 arcsec step).

    PACS_CAL_26_0 Photometer
    • The PACS photometer flux calibration has been re-derived. Absolute fluxes of point-sources will change by less than 5%, extended sources will change by 10-20%.
    • Aperture photometry of point-sources requires from now on the application of new aperture correction factors, taking into account that there is still significant flux beyond 60 arcsec. These new correction factors (together with the old ones, applicable for PACS photometer observations calibrated with the old version of the Response calibration file in PACS calibration file set v16 or older) are stored in: "PCalPhotometer_ApertureCorrection_FM_v2.fits" and can be retrieved via the new task "photApertureCorrectionPointSource" to be applied after "annularSkyAperturePhotometry" in hipe 7.0 or later.
      Users of earlier versions of hipe can use the aperture corrections listed in the PACS photometer point-source flux calibration report, available at the PACS instrument page on the HSC web pages.
    • Invntt calibration files, used in the madmap map making, updated to v4. Version 4 of Invntt contains the values of version 1, but in a new format needed by a software update.
    • New calibration product: DetectorReadoutTimeShift. Currently not used in the pipeline processing.
    • New calibration product: CoolerRecyclingTimes. Currently not used in the pipeline processing.

    Spectrometer

    • capacitance ratios updated, relevant for high flux source observations
