VLBASRT is defined in the VLBAUTIL run file. ---------------------------------------------------------------- VLBASRT Type: Procedure Use: VLBASRT is a procedure that will sort and index VLBA data, if necessary. Type RUN VLBAUTIL to make the VLBASRT procedure available. NOTE: NEVER ABORT THIS PROCEDURE WHILE IT IS RUNNING, IT COULD CAUSE YOUR ORIGINAL DATA FILE TO BE DESTROYED. 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. 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. ---------------------------------------------------------------- VLBASRT: Procedure to look for subarrays Documentor: Amy Mioduszewski Related Programs: MSORT, INDXR, VLBAUTIL Use VLBASRT if you FITLD or VLBALOAD has produced messages that say that there may be a subarray condition or the data may be out of order, but you know that you do not have subarrays or if you just know your data needs to be sorted. VLBASRT will check if your data needs sorting and if so the data is sorted with MSORT; then it checks if your data has the first calibration (CL) and index (NX) tables, and if not creates them by running INDXR. NEVER ABORT THIS PROCEDURE WHILE IT IS RUNNING, IT COULD CAUSE YOUR ORIGINAL DATA FILE TO BE DESTROYED. You should run VLBASRT 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. VLBASRT is intended for all levels of VLBA users.
