Done for the day after this (observing tonight) two new procedures:
alignment_offsets_to_ncdf.pro calcoeffs_to_ncdf.pro
they're really easy, very nearly one-liners. Once they've been used once, you can just use ncdf_varput_scale Modified keyword parameters in do_the_pointing: offsets will always be applied unless the keyword 'no_offsets' is passed into the code (or the top-level wrapper). Since offsets default to zero, this should be OK.
