[daip] fillm problem

Dear Eric,
we ran into an odd FILLM problem when loading AC713 15mar04 data. When
loading with no time range AIPS reports finding data on both the
calibrator and the source, but no calibrator data appear in LISTR/SCAN
(even if one runs INDXR later). If one sets a time range to start loading
data a few minutes into the file (at midnight...), the resulting data set is
fine. There were odd things going on at the VLA (ANTSOL crashed, timing
problems, etc. etc. -- check Pat Van Buskirk for details) so this sort of
strange behavior is perhaps not surprising.
Given all this weirdness it's not clear whether you want to consider this
a FILLM bug or a fluke. I've appended the inputs to FILLM and the LISTR
output in case you do want to track this down. The data are available on
agave's ftp site, called AC713* (two files). Please let Meri know if you
decided *NOT* to go after this, as she will then want to delete those files.
Cheers,
Michael (analyst for a day???)
