FIXRL: swaps R and L polarizations for some antennas
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 #.
VPARM 0.0 List of antennas to swap
DOTABLE -1.0 1.0 >= 0 > swap SY, TY, CD tables
FQCENTER >= 0 -> center frequency axis
HELP SECTION
FIXRL
Task: This task swaps the R and L polarizations for a list of
antennas (i.e. those that were mis-wired during the particular
data session).
NOTE: this task does not swap polarizations in calibration
tables (SN, CL, BP, etc etc) so it should be run before any
calibration tasks. They will not work correctly on swapped
antennas anyway.
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.
VPARM......List of antennas to swap - a 0 terminates the list.
DOTABLE....>= 0 -> swap polarizations in monitor tables (SY, TY, and
CD) only. < 0 -> no table swap.
FQCENTER...> 0 => Change frequency axis reference pixel to
Nchan / 2 + 1
else => do not change reference pixel
