TI2HA     Task to change times to hour angles
INNAME                             Input UV file name (name)
INCLASS                            Input UV file name (class)
INSEQ             0.0     9999.0   Input UV file name (seq. #)
INDISK            0.0        9.0   Input UV file disk unit #
OUTNAME                            Output UV file name (name)
OUTCLASS                           Output UV file name (class)
OUTSEQ           -1.0     9999.0   Output UV file name (seq. #)
OUTDISK           0.0        9.0   Output UV file disk unit #.
DOARRAY          -1.0        1.0   > 0 => subtract 5 days from
                                   times for subarray number

TI2HA
Task:  This task will copy an entire data set replacing the IAT time
       with the hour angle (biased by one day to avoid negatives).
       The output should not be used for any form of self-calibration
       since times from multiple days can be confused.  The task works
       on single-source data sets only because of the importance of
       correct times to multi-source data handling.  This task is
       envisioned as allowing users to average data taken at the same
       times and with the same arrays over multiple days.  The averaging
       can then be done (after a UVSRT or MSORT) with UBAVG, UVAVG, or
       AVER.

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.
  DOARRAY....Times are often altered by DBCON by adding
             5*(subarray#-1).  If DOARRAY>0 and the time is suitable,
             this offset will be subtracted before the hour angle is
             determined.
