DSORC: Renumbers selected source numbers
INPUTS
INNAME Input UV file name (name)
INCLASS Input UV file name (class)
INSEQ 0.0 9999.0 Input UV file name (seq. #)
INDISK 0.0 9.0 Input UV file disk unit #
OUTNAME Output UV file name (name)
OUTCLASS Output UV file name (class)
OUTSEQ -1.0 9999.0 Output UV file name (seq. #)
OUTDISK 0.0 9.0 Output UV file disk unit #.
APARM Source numbers to be changed
BPARM into these numbers
FQCENTER >= 0 -> center frequency axis
HELP SECTION
DSORC
Task: This task will renumber data samples with source number
APARM(i) (i = 1:10) into BPARM(i). This will repair an
excessive separation of sources due to (for example) slight
position differences. The output file may be the same as the
input file.
Be very careful with APARM and BPARM. If a BPARM(i) source
number exists in the SU table and is not being changed in the
APARM list, then the APARM(i) SU table record will not be
changed. Note too that this task will allow you to completely
mess up your data set.
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 file. 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 file. 0 => highest with
space for the file.
APARM......Input source numbers to be changed
BPARM......into output numbers. APARM(1) is changed into BPARM(1),
APARM(2) into BPARM(2), etc. No meaningful default
(BPARM(i) <= 0 -> 1). No default for APARM.
FQCENTER,..> 0 => Change frequency axis reference pixel to
Nchan / 2 + 1
else => do not change reference pixel
