VLBASUBS: Procedure to look for subarrays in VLBA data
INNAME Input file name
INCLASS Input file class
INSEQ Input file sequence number
INDISK Disk number for input file
SUBARRAY 0.0 1000.0 1 -> put everything into one
2 -> automatically split into
CLINT CL entry interval (min)
0 => 0.25 minute.
VLBASUBS is defined in the VLBAUTIL run file.
Use: VLBASUBS is a procedure that will look for subarrays in VLBA data.
Type RUN VLBAUTIL to make the VLBASUBS procedure available.
INNAME.....The name of the file to be corrected. Wildcard characters are
INCLASS....The class of the file to be corrected. Wildcard characters are
INSEQ......The sequence number of the file to be corrected. Zero defaults
to the highest sequence number matching INNAME, INCLASS, and
INDISK.....The disk drive number of the file to be corrected. Zero defaults
to any disk.
SUBARRAY...1 -> FITLD says there are subarrays but there are no real
subarrays in the data
2 -> Data will be automatically searched for subarrays and
subarrays will be created if found.
CLINT......Calibration table interval in minutes. This should normally be in
the range 0.25 to 1.0 and is used when the calibration table is
regenerated. A calibration interval of 0.25 minute will be assumed
if this is less than or equal to zero.

WHEN TO USE VLBASUBS
Use VLBASUBS to find subarrays in VLBA data. VLBASUBS will
check whether there might be more than one subarray present in
the data and if so will make sure that the data are sorted
correctly (MSORT), check for subarrays (USUBA), and then
rebuild the calibration (CL) and index (NX) tables (INDXR).
You should run VLBASUBS after you have finished loading the data
from tape but before you either change the polarization
structure of the data with FXPOL, load any calibration data for
non-VLBA telescopes, or apply the calibration data.
VLBASUBS is intended for all levels of VLBA users.
