Observing with PACS

PACS photometer

PACS photometer data processing

  • The corresponding PACS Data Reduction Guide (PDRG) is PDRG version 6.

  • Data reduction scripts are now available in HIPE under the menu: Pipeline --> PACS --> Photometer - Scan map & mini-map

PACS photometer calibration

  • PACS photometer photometry calibration: The current photometry accuracy based on version 5 of the responsivity calibration file is believed to be better than 10% for point-sources. It is currently being refined to target the 5% accuracy, but it will only be available in HCSS 7. Important: the encircled energy fraction (EEF) for point-sources corresponding to this energy scale are available in the above note "PACS Photometer : chop/nod point-source & mini-scan map AOT release note", the colour correction factors as well. Note: The EEF to be used for photometry is consistent with version 5 of the responsivity calibration file, with a PSF normalization at 1 arcmin, and not with the latest PSF libraries posted above.

  • Extended emission photometry: it is believed to be consistent with IRAS and SPITZER to better than 20%. To match with with other instruments/missions the use of the right convolution kernel is critical.

  • Point-source observations:

  • Scan map observations: PACS Scan Map AOT release note 23 February 2010. This technical note is somewhat outdated, the correction factors for the photometry shall not be applied anymore since the HCSS track 4.
