OUTDISK Disk number for output files 0 => highest with space VLBAFQS is defined in the VLBAUTIL run file. ---------------------------------------------------------------- VLBAFQS Type: Procedure Use: VLBAFQS is a procedure that copies each frequency ID in an input file to a separate output file. Each output file has the same name as the input file and class 'FQ-n' where n is the frequency ID. If the input file contains only one frequency ID then no new files will be created. INNAME.....The name of the input file. Wildcard characters are allowed. INCLASS....The class of the input file. Wildcard characters are allowed. INSEQ......The sequence number of the input file. Zero defaults to the highest sequence number for a file matching INNAME, INCLASS, and INDISK. INDISK.....The disk drive number of the input file. Zero defaults to any disk. CLINT......Calibration table interval in minutes. This should normally be in the range 0.25 to 1.0. A calibration interval of 0.25 minute will be assumed if this value is negative or zero. Use the same value that you used in VLBALOAD or FITLD. OUTDISK....If positive then all output files will be written to the specified disk. If zero then output files will be written to the highest disk with sufficient space (this may be different for each output file) ---------------------------------------------------------------- VLBAFQS: Procedure to copy frequency IDs to separate files Documentor: Chris Flatters Related Programs: VLBAUTIL, UVCOP, INDXR, VLBAFIX VLBAFIX is the more modern of these procedures, it includes VLBAFQS as well as other procedures which "fix" (sort, index etc.) the data after it is loaded, so you are encouraged to use VLBAFIX rather than VLBAFQS. WHEN TO USE VLBAFQS Use VLBAFQS to split data with different frequency into separate files. Most AIPS tasks can only handle a single frequency at a time so there is no benefit to keeping more than one frequency in a file. VLBAFQS will normally be run after searching for subarrays (VLBASUBS) and before fixing polarization labels (VLBAFPOL). NOTE: This program will split the frequencies in experiments where S band (13 cm) and X band (4 cm) or 90 cm and 50 cm are observed simultaneously (as well as multiple FREQIDs). However, it WILL NOT split data where 90 cm, 50 cm and 18 cm are observed simultaneously.
