SBCOR: Task to correct VLBA data for 130 deg. phase shift
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 #.
BCHAN 0.0 9999. Channel at which LSB begins
ECHAN 0.0 9999. Channel at which LSB ends
APARM Control info:
1: => phase-shift between
sidebands (degrees),
0 => -130 degrees
ANTENNAS Antennas to correct.
HELP SECTION
SBCOR
Task: This task is designed to correct VLBI data recorded
with VLBA record terminals for the phase shift that
occurs between lower and upper sidebands.
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 w room
BCHAN......Channel at which LSB begins - no default
ECHAN......Channel at which LSB ends, 0=> last channel
APARM......(1): The actual phase-offset between the lower
and upper sidebands. If zero assumes the
lower sideband is wrong by -130 degrees and
will adjust the data accordingly. If non-zero
will use the value given as the phase-offset.
ANTENNAS...A list of all antennas which observed and recorded
with a VLBA terminal. The baselines to these antennas
will have the 130 degree phase shift inserted in the
data.
