[daip] Primary Beam Correction

[Frazer Owen]

    Eric,

    I am trying to use JMFIT on some 610 MHz GMRT data. By the way,
Leonia's modification of UVAVG works wonderfully and makes an
amazing improvement on the image.

    Anyway, I wanted to make the primary beam correction, so I entered
the PBPARM's from their webpage. The actual values are

AIPS 2: PBPARM       0.05         1        Primary beam parameters:
AIPS 2:              -3.486      47.749    (1) level to believe - <= 0
AIPS 2:             -35.203      10.399    means do not apply a primary
AIPS 2:               0                    beam (2) > 0 use (3)-(7)

    This all may have worked fine. However, I get a message in the
output about having used a VLA antenna for GMRT. Is this
just misleading or did something fail ?

    Hope you are doing OK.

    best wishes,

    Frazer
