Calibrate SCUBA-2 data
This recipe may be used to convert between different (known) calibration types, e.g., from mJy/arcsec∗∗2 to mJy/beam and vice versa.
The input data must not have the same units as the desired calibration.
All input data will have the same calibration applied.
The FCF FITS header will be updated with the value used to calibrate the data. The units will be in the comment.
Creates an output file for each calibrated input file with suffix _cal.
