VLBASUBS is defined in the VLBAUTIL run file. ---------------------------------------------------------------- VLBASUBS Type: Procedure 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 allowed. INCLASS....The class of the file to be corrected. Wildcard characters are allowed. INSEQ......The sequence number of the file to be corrected. Zero defaults to the highest sequence number matching INNAME, INCLASS, and INDISK. 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. ---------------------------------------------------------------- VLBASUBS: Procedure to look for subarrays Documentor: Chris Flatters Related Programs: MSORT, USUBA, INDXR, VLBAUTIL 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.
