HELP SECTION

TBAVG
Task:  This task averages visibility data over a specified averaging
       time, combining all baselines.  The results are written to an
       output file with each visibility labeled as baseline 1-2.  This
       is useful for measuring time variable point source flux
       densities at the phase center of the data.  Your data shold be
       prepared carefully for this operation.  TBAVG applies to
       single-source data files and does not apply calibration and
       flagging, does not select on source names, IFs, or channels.
       If the field you are observing contains multiple objects, the
       time-constant objects should be removed using UVSUB before
       running TBAVG.  Autocorrelation data are omitted.

       Task DFTPL makes a plot of the real parts of the visibility
       averages rather than writing a UV data set.
Adverbs:
  INNAME.....Input UV file name (name).      Standard defaults.
  INCLASS....Input UV file name (class).     Standard defaults.
  INSEQ......Input UV file name (seq. #).    0 => highest.
  INDISK.....Disk drive # of input UV file.  0 => any.
  OUTNAME....Output UV file name (name).     Standard defaults.
  OUTCLASS...Output UV file name (class).    Standard defaults.
  OUTSEQ.....Output UV file name (seq. #).   0 => highest unique
  OUTDISK....Disk drive # of output UV file. 0 => highest with
             space for the file.
  SOLINT.....The averaging time in seconds.  Data on all
             baselines will be averaged together for this
             period.
  SHIFT......Shift in arcseconds.  The data are shifted and then
             averaged.  These are shifts in arc seconds at the
             reference point -
             RA = RA0 + SHIFT(1)/cos(DEC0), DEC = DEC0 + SHIFT(2)
