[daip] Fluxcal missing in the data

[Kamble, Atish]

Dear Eric,

I've experienced this quite a few times now: The data loaded in AIPS
doesn't show fluxcal visibilities although archive does show record of
fluxcal observations and also the BDFLIST records. Any idea what's wrong ?

For example, here is a part of the output from LISTR. Notice the 0
visibilities for 3C147 ! The fluxcal 3C147 was observed according to the
observation scans and also from the fact that LISTR detects it as one of
the listed sources in the FITS file.

5 3C147 : 0000 N 05:42:36.1379 49:51:07.234 0
#----------------------------------------#

The files were downloaded from the VLA archive and loaded into AIPS using
BDF2AIPS task.

Help would be highly appreciated.

Here is another case from a different data-set. In the following LISTR
output please note that there are THREE different "calcodes" (D, N and D)
out of which only those calibrators corresponding to calcode 'D' have been
loaded. Calibrators with code 'N' have been omitted out as a result much of
the fluxcal observations ain't accessible ! Is this the archive issue or
AIPS ? Why is this happening ?

I have written to the helpdesk too. I don't know if that's a separate team
handling archive. So bringing it out here too to the AIPS experts. Sorry
for the duplication, if you are receiving this multiple times.

Thanks,
