[daip] Problem with fittp and fitab

[Charles Figura]

So Pat Murphy recommended that I email here for help, and I know he 
copied you in on my exchange, but I thought I'd follow up with that.  I'm 
trying to write out a data cube with AIPS, following a technique that Jay 
Lockman taught me - converting an IDL fits file to a uvfits, using uvlod to 
bring it into AIPS, gridding it up with sdgrd, and writing out a fits image 
with fittp.

I ran into a problem the other day after successfully using this process to 
output a 662-position cube (roughly 30x30) with 27 channels.  This 
dataset had been smoothed & decimated, and I thought I'd put together 
a less- or non-smoothed cube as well.

Every attempt (one with 50 channels, one with 200) has met with the 
same AIPS error message when I tried to write out the image with fittp:

AIPS 1: Resumes   

I'm not sure exactly what the error message *means*, but it seems to 
indicate that -something- was too big (or bigger than AIPS thought it 
should be, at least).  Jay's told me that he's done much larger cubes (on 
the order of 512x512x1024, so it hardly seems that it should be a matter 
of size, but I'm at a bit of a loss.  I don't see *anything* in my data that 
seems like it should be causing a problem.

Any ideas?  I'd be most grateful for help, and more than happy to supply 
any diagnostic information that might help figure this out.

Thanks!

-Charlie
