Hi Eric.
I used DBCON on a lot of files last night and although I wasn't going to
exceed 50, I first wrote the files out to disk and back in again with
FITLD in order to get them in the new FITS format. I then mapped and
self-calibrated, but CALIB complains about quite a few of the subarrays
being missing and LISTR confirms this.
Actually, all the data appear to be present, but some subarrays are
being mislabelled. See attached LISTR output.
If I just run DBCON with the files in original FITS format, there are no
problems.
I haven't tried DBCONing >50 files yet, but will soon.
