HELP SECTION

UBAVG
Type:  Task
Use:   Baseline dependent time averaging of uv data.  The
       averaging time is set by the field of view desired and a
       specified maximum averaging time.
       NB: data must be sorted to 'BT' order before running.
Adverbs:
  INNAME.....Input UV data file (name).     Standard defaults.
  INCLASS....Input UV data file (class).    Standard defaults.
  INSEQ......Input UV data file (seq. #).   0 => highest.
  INDISK.....Input UV data file disk #.  0 => any.
  OUTNAME....Output UV data name (name). Standard defaults.
  OUTCLASS...Output UV data file (class).
  OUTDISK....The disk # of output data.  0 => highest
             with space.
  OUTSEQ.....Output sequence number. 0 => new file.
  APARM.....Task enrichment parameters.
            (1)  This gives the maximum averaging time in
            seconds, 0=> infinite.
               This parameter may be necessary if subsequent
            editing or self calibration is required.

            (2)  This is the desired field of view (radius) which is
            not to be distorted due to time averaging in minutes of
            arc.   0 = > 20.
               The field of view is the region in which averaging is
            not to reduce the amplitude by more than 1 percent on any
            baseline.  No data separated by more than 268.5
            wavelengths divided by APARM(2) are averaged together.
            sinc(.0781) = 0.99 and .0781 * 60 *180 / pi = 268.5.
  BADDISK...Disk #'s to avoid for scratch files
