Specifically, for space VLBI, antennas used as tracking stations can be renumbered as one antenna corresponding to VSOP. To be used when most space VLBI specific-calibration is completed. Do this very carefully, but you can renumber a bunch of antennas at the same time. In fact if you want to swap antenna numbers 2 and 14 (say) then you must do that in the same job with ANTEN = 2,14; BASELINE = 14,2 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. 0 => any. OUTNAME....Output UV file name (name). Standard defaults. OUTCLASS...Output UV file name (class). Standard defaults. OUTSEQ.....Output UV file name (seq. #).0 = > highest unique. OUTDISK....Disk drive # of output UV. 0 => highest with space If the outfile specification equals the infile specification, the output data file will overwrite the input data file. SUBARRAY...Subbarray whose antennas are to be renumbered. Only one subarray may be processed at a time. 0 => subarray 1 . ANTENNAS...List of new antenna numbers. BASELINE...Corresponding list of old antenna numbers. ---------------------------------------------------------------- RESEQ: Task which resequences antenna numbers DOCUMENTOR: K.M.Desai (NRAO/VLA), Eric W. Greisen RELATED PROGRAMS: NONE PURPOSE RESEQ will convert all antenna numbers specified through the BASELINE adverb to those specified by the ANTENNAS adverb. This is expected to be useful for space vlbi work. COMMENTS OUTNAME, OUTCLASS, OUTSEQ, OUTDISK: If the outfile specification is identical to the infile specification (including defaults used in both file specifications), then the sorted data will overwrite the input data. Make sure the input data set is properly backed up before you overwrite since a computer crash may destroy the input data set. SUBARRAY: Only antennas in a single subarray are processed in one run of RESEQ. The subarray is chosen via this adverb. SUBARRAY 0 defaults to SUBARRAY 1. ANTENNAS: The output antenna numbers. If ANTENNA(i)=0, ANTENNA(1) is used. BASELINE: Input antenna number BASELINE(i) is renumbered ANTENNA(i). A complicated pattern is legitimate, e.g. ANTENNAS 1,2,3,4,5,6,7,8,9,10 BASELINE 3 5 7 9 2 4 6 8 10 1 to renumber all of the antennas in a VLBA data set.
