UVNOU: Task which flags points close to the U = 0
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 #.
UVRANGE (1) Minimum U distance
(2) Minimum V distance
(wavelengths)
HELP SECTION
UVNOU
Task: This task flags UV data which is less than UVRANGE(1)
wavelengths from the U axis and UVRANG(2) wavelengths
from the V axis. Since the fringe rate is 0
on the V axis (u = 0), the rejection by averaging of
unwanted terrestrial signals due to interference,
and other bad data, fails near U = 0. This
task is very useful for removing that piece of the UV
plane which might be corrupted. Contact Tim Cornwell
or Juan Uson for any advice.
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.
UVRANGE....(1) Minimum u distance allowed (wavelengths)
[ =0 => defaults to 10^20 wavelengths]
(2) Minimum v distance allowed (wavelengths)
[ =0 => defaults to 10^20 wavelengths]
ie, all data within UVRANGE(1) of the U axis AND
within UVRANGE(2) of the V axis will be flagged.
