PACS calibration file set v78 incorporates the following differences from the previous community release, v77.

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 following calibration products have been updated:
