I believe that CONVL does the correct thing with FACTOR=0.  They should 
be fine.

The resolution of the optical image and its units are your problem - it 
is your image.  Ask the people who took it, Try PRTTP on the FITS file 
with PRTLEV=2 - there may be all sorts of info in the header (or use 
PRTHI on the aips image on disk) in keywords aips does not recognize.
