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. #)

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.
