IR Imaging ========== Two data files have units of milli-Jy rather than micro-Jy. Is this right? What should we do about files 0033-34, where one is an error map of the other? Also 0055-56,57-8, 59-60. And what's going on with the raw data where one is noted as "SOURCE BEAM" and the next as "REFERENCE BEAM"? Several files in the 0060 range have comments that provide the UT range, but the OBSERVATION_TIME noted in the FITS header, which is allegedly the midpoint of the observation, is NOT in that range! There are a mix of files in here - some raw, some calibrated, some calibration observations (including point spread functions). Not clear what the structure should be. In at least some cases it might be appropriate to either rename files so related halves of pairs are immediately visible, and/or move the calibration files into the calib/ directory. The index should probably contain a few additional useful fields: PROCESSING_ID, FILTER and UNIT, for example.
