[daip] 31DEC03 question

Eric or other DAIP,
The Christmas elves appear to have been working on my computer,
because when I cleaned everything off and tried to install 31DEC03
again to get a reliable error log to send you, the damn thing
compiled with no errors!
That's good. What isn't good is that when I tried to read in a
FITS file from an old dataset, just to see if I could run a couple
of basic tasks on it, UVPLT would not run at all, and UVPRT thought
it ran successfully, but did not show any data, although the header shows
8546 visibility data being present. The UV-FITS file in question is
attached, and the inputs for UVPLT are indicated below. I also tried
Stokes = 'LL' and Stokes = 'RR' with the same result.
We are running Mandrake 9.2.
Any help you can give will be most appreciated!
Best regards,
Denise
