HA2TI
Task:  This task will convert a data set which has been processed by
       TI2HA into hour angles, such as inside the procedure STUFFR,
       back into real times.  Proper times are needed for computations
       such as those in UVFIX or to determine parallactic angle to be
       used in imaging, etc.
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.
  REFANT.....Reference antenna.  Specify an antenna to assume that all
             hour angles are with respect to that antenna.  If 0, then
             hour angles are converted wrt the lower numbered antenna
             of EACH antenna pair.  TI2HA used to do REFANT=0, but now
             also offers the REFANT option.  Use the same antenna in
             both.
