VLBSY: Task which reads total power information

INPUTS

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 #
CALIN                              Text file name.

OUTVERS           0.0    46655.0   Output SY table, 0=>new table
                                   If selected table exists, the
                                   new data are added to it.
DOKEEP           -1.0        1.0   > 0 -> keep records which are
                                   not in any scan

HELP SECTION

VLBSY
Task:  This task reads an ascii file containing total power
       information .  It reads the modern DiFX created file which
       has a simple format, converting it to an SY table.

       Switched power data live in
          /home/vlba/metadata/switchedpower
       and subdirectories thereof if older than x (where x is
       currently Walter
       manually cleaning up)

          The DiFX file(s) may consist of a single file, with the
       multiple initial files simply concatenated.  Or they may
       consist of a file for each antenna.  In that case the file
       names must end in an underscore followed by the 2-character
       antenna name.  Specify CALIN up to and including the underscore.

          The UV data set must exist and is used to convert antenna
       names to antenna numbers and times to source and FQID numbers.
       The code will adopt sensible defaults if the input data set is
       not specific to the current SY table.
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.
  CALIN......Total power text file.
             If the name ends in an _ (underscore) the the files with
             BR, FD, HN, ... SC will be read in order and having a
             file missing will generate a warning but not a failure.
  SUBARRAY...Subarray number                 0 => 1
  OUTVERS....Desired output SY table.
             0 means create a new SY table under following number.
             If selected table exists, the new data added to it
  DOKEEP.....> 0 => keep all records found even if they do not appear
                    in any of the scans in the index (NX) table.  The
                    source number on such records is 0.
             <= 0 => omit such records from the PC table.
  BADDISK....The disk numbers to avoid for scratch files (sorting
             tables mostly).
