HELP SECTION

REWGT
Task:  This task will rescale uv data weights by a user-supplied
       factor.  The factor may be different for different subarrays or
       different IFs.  See task REAMP to scale uv data amplitudes with
       corresponding changes to the weights  REWGT can also read a
       text file with weight factors in it.  That file can be written
       by RFLAG and is in the form used with BOXFILE in IMAGR.
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.
  OPTYPE.....'SUBA' scaling array applies to subarrays 1-64
             'FILE' scaling found in text file INTEXT
             other  scaling array applies to IFs 1-64
  PBSIZE.....Scaling array: multiply subarray n by PBSIZE(n) on OPTYPE
             'SUBA', else multiply IF n by PBSIZE(n).
  SUBARRAY...Limit scaling to specified subarray on OPTYPE 'FILE' and
             other.  All subarrays are copied.
             0 -> all subarrays are scaled.
  BIF........Limit scaling to IF BIF on optype 'SUBA'.  0 -> all
             and all IFs are copied anyway.
  INTEXT.....Weight array text file.  Each line has the form
             W  weight  chan   IF
             with the W in column 1.  IF blank or 0 means all IFs.
             Channels not specified get scaling factor 1.0.
  FQCENTER,..>  0 => Change frequency axis reference pixel to
                     Nchan / 2 + 1
             else => do not change reference pixel
