HELP SECTION

PCLOD
Task:  This task reads an ascii file containing phase (pulse)
       cal, cable cal and state count data generated by the
       VLBA monitor system (or by hand if you really, really
       want to do such a thing). It is purely a format transfer
       task, just producing an AIPS PC table which is a copy of
       the data in the ascii file.
         Phase cal data from VLBA antennas is included in FITS
       files from the VLBA correlator from April 1 1999 onwards.
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......Phase (pulse) - cal text file.
  SUBARRAY...Subarray number                 0 => 1
  FQTOL......Freq. tol. in IF match (KHz)    <=0 => 0.1*WBAND
                                             works in majority cases
  OUTVER.....Desired output PC table.
             0 means create a new PC table under following number.
             If selected table exists, the new data added to it

PCLOD : Reads pulse-cal info into AIPS PC table.

                        COMMENTS

Phase calibration information for VLBA antennas is included in FITS
files from the VLBA correlator from April 1 1999 onwards.  PCLOD need
only be run to load amplitude calibration data that was not
transferred automatically.

CALIN:
     PCLOD requires an ASCII file containing the VLBA pulse
calibration data. This file has the format given below and can be
obtained from the VLBA correlator (the VLBA technical contact person
assigned to the project can provide information in this regard).

     The are two type of "groups" in the PCLOD ascii file.
A FREQUENCY group that describes the frequency structure of the
table and a PULSE group that contains the data.
The format of a file is shown below:
