Community Release Note for PACS Calibration Set v69

PACS calibration file set v69 incorporates the following differences from the previous community release, v65:

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 changes.

Affected observations & processing

• Spectrometer: level-2 drizzle products and results of the specExtendedToPointCorrection task.
