MORIF
Task:  This task is designed to change a data set with multiple
       spectral windows each having multiple spectral channels into a
       data set with NPIECE times as many spectral windows ("IFs")
       each with 1/NPIECE times as many spectral channels.  Some
       calibrations and normalizations are done on an IF basis (e.g.,
       CALIB solutions, BPASS normalizations) and this task allows
       those to be done over a smaller range of frequency or spectral
       channel number.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.
  BIF........Lowest IF (spectral window) included.  0 -> 1.
  EIF........Highest IF included.  0 -> max IF.
  BCHAN......Lowest channel included
  ECHAN......Highest channel included - used to allow NPIECE to work.
  NPIECE.....Integer nuber of equal pieces in which to break up each
             spectral window.  Only certain values are allowed.  If
             there are 64 spectral channels then NPIECE must be 2, 4,
             8, 16, or 32.  If there are 63 spectral channels then
             NPIECE must be 3, 7, 9, or 21.
  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.
