Photometry

  • There is a a new task photCoverage2Noise, run in the SPG pipeline to derive an error map from the coverage map, including the correction for correlated noise.
Added:

  • The task MaskFromCatalogueTask allows to build a mask from a source list; a very useful task for deep imaging, to properly mask even faint point-sources for highpass filtering.

Calibration

Photometry

Changed:
<

  • There is no change in the PACS photometer calibration since Hipe 9 and version 9 of the calibration tree.

>
  • There is no change in the PACS photometer calibration since Hipe 9 and version 41 of the calibration tree.
 

Spectroscopy

  • In order to be less sensitive to (on average) mispointed flux calibration observations, the flux calibration scheme has changed: the construction of the calibration tables is now based on the standard calibrators fluxes coming from the central 9 spaxels instead of the central one only. This implies that two new calibration tables were introduced in the calibration tree, namely observedResponse3x3 and calSourceFlux3x3. Those tables are used by default in specDiffCs and should lead to more reliable fluxes, notably in case of mispointed observations. An optional parameter, use3x3 (True by default), was added to specDiffCs. You can still use the former calibration scheme by setting use3x3 to False although it is not recommended.
