<DIV> I'm running IMAGR with a couple of fields. The first
field looks about right with a maximum of 1.0 Jy for the beam but the second
field beam has a maximum of 4.0 Jy. How can this be? Aren't the
beams meant to have unity maximum? Or is there some additional weighting
that has to happen? The sum of the gridding weights in both cases is the
same so what's going on here? (PRTMSG capture appended.)
</DIV>

<DIV> Another issue: I have concatenated multiple VLBA
datasets together to improve my sensitivity. The configuration of the
arrays in most of the datasets is the same but not always. Consequently,
the antenna numbering scheme for each sub-array changes --- say, if one antenna
was unanvailable. If I run CALIB on this multi-epoch database, CALIB
reports that some antennas get flagged because they can't be tied across
sub-arrays. This shouldn't happen, I think, because all we need is that
the sub-set of antennas in each effective sub-array at each epoch should be
linked. I don't remember this sort of behavior with VLA multi-epoch data
so is there something different happening when a non-VLA array is
involved? </DIV>
