Community Release Note for PACS Calibration Set v77

PACS calibration file set v77 incorporates the following differences from the previous community release, v72:

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.

Photometer

• No changes.
