RESEQ: Task which renumbers antennas
INNAME Input UV file name (name)
INCLASS Input UV file name (class)
INSEQ 0.0 9999.0 Input UV file name (seq. #)
INDISK Disk unit # of input UV data
OUTNAME Sorted UV file name (name)
OUTCLASS Sorted UV file name (class)
OUTSEQ -1.0 9999.0 Sorted UV file name (seq. #)
OUTDISK Disk unit # of sorted UV data
0 => highest with space
If outfile spec. equals the
infile spec., output will
overwrite the input
SUBARRAY Subarray to be renumbered
ANTENNAS 0.0 New antenna numbers
BASELINE 0.0 Old antenna numbers
Use: Generally, to renumber antennas. 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
ANTEN = 2,14; BASELINE = 14,2
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 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.
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
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.
The output antenna numbers. If ANTENNA(i)=0, ANTENNA(1) is used.
Input antenna number BASELINE(i) is renumbered ANTENNA(i). A
complicated pattern is legitimate, e.g.
BASELINE 3 5 7 9 2 4 6 8 10 1
to renumber all of the antennas in a VLBA data set.
