VLBCD: 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.
SUBARRAY                           Subarray number (0=>1)
OUTVERS           0.0    46655.0   Output CD table, 0=>new table
                                   If selected table exists, the
                                   new data are added to it.
BADDISK                            Disks to avoid for scratch

HELP SECTION

VLBCD
Task:  This task reads an ascii file containing VLBA calibration
       information.  The usual file for this data is found at
           /home/vlbiobs/astronomy/apr21/ta035i/ta035ical.vlba
       where this example is for project TA035I observed in
       April 2021.
          The UV data set must exist and is used to convert antenna
       names to antenna numbers.
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......Calibration text file
  SUBARRAY...Subarray number                 0 => 1
  OUTVERS....Desired output CD table.  Normally, no CD table
             exists and this task creates version 1.  It is not
             good to add data unless CALIN contains new antennas.
  BADDISK....The disk numbers to avoid for scratch files (sorting
             tables mostly).

EXPLAIN SECTION


The task looks for a line beginning with "TSYS" followed by the
antenna name.  It then expects a blank comment line ("!") and
a second comment line with the antenna name, project name, first
source name, and time range.  This is followed by two times the
number of IFs lines giving the noise tube values associated with
the two p[olarizations and each IF.  The IFs are given by the
center frequency in the Spectral Window (IF).

E.g.

TSYS  BR  timeoff = 0.0  FT = 1.0 /
