[daip] UVSUB: Subtracting all the Stokes contributed by point sources from the UV data

[Wasim Raja]

Dear Eric
  In continuation to my query below:
  Does UVSUB do something to the ANTENNA-BASELINE
  Numbering scheme? I get this error (last line in the output
  below) when I try to load the FITTP-ed AIPS UVSUB data
  into MIRIAD:
  [The AIPS version I am working on is 31DEC10]

>Fits: version 1.1 09-Feb-07
>### Warning:  Unable to guess typical system temperature
>### Warning:  Unable to guess typical system gain
>Assuming feed angle is 0 degrees
>### Warning:  Insufficient information to determine parallactic angle
>Reading AIPS AN table
>Decrementing times for configuration  1 by 33.0 seconds (IAT-UTC).
>Reading AIPS FQ table
>Data are circularly polarized
>Reading the correlation data
>### Fatal Error:  Illegal baseline number in antbas

thanks
