[daip] UV files and FILLM

[Stockdale, Christopher]

Amy,

I think I have figured out the root problem after talking with Meri.
We were observing for 26 hr stretch.  We flux cal'ed early and late in
the run.  

While observing, antennae were being moved.  As antennae got put into
the array, it caused a new antenna table to be creating, forcing a new
multisource data set to be created, without matching flux cal data,
because the array had changed in mid-run. 

Can I merge the UV data sets, flagging out the offending antennae?  How
does one do this?

Hi Chris,

I am not sure I understand the problem.  How is FILLM splitting
up the data?  Is different time ranges in different files or
different frequencies in different files?

If it is different times, I think I understand the problem.  FILLM
has been changed so that if an antenna changes positions in the AN
table then FILLM will start a new file with a new AN table.  You
should compare your AN tables and see which antenna(s) moved.  You
can do one of two things, either calibrate the data separately and
SPLIT and DBCON, or you can delete the offending antenna(s) and
DBCON before calibration.

DBCON concatenates datasets, VBGLU glues together frequency
bands.

Cheers,

Amy
