My colleague, JoAnn O'Linger, and I have 12m OTF data for several runs from 
2000 - early 2002. A good portion of these data were never loaded into AIPS.
I can't speak for JoAnn, but I'm still running AIPS version 31DEC01...
I'm hoping that the software for this older version WILL support loading the
older files and creating the appropriate OTFUV, etc files. Once this is done, I
intend to write out all important data to FITS files!

OK - I think I'll give the first method a try first.

Will do, and thanks! Looks like I shouldn't upgrade AIPS until I've got this
batch of data safely processed, huh?

Thanks again,
