AIPS HELP file for PCLOD in 31DEC09
As of Sun Nov 22 17:04:05 2009
PCLOD: Task which reads pulse-cal 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)
FQTOL Freq. tol. in IF match (kHz)
<=0 => 0.1*WBAND
works in majority cases
OUTVER 0.0 46655.0 Output PC table, 0=>new table
If selected table exists, the
new data added to it.
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
EXPLAIN SECTION
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:

! A ToneSkyFreq of 0.00 means that that tone number carries
