HELP SECTION

UVCMP
Task:  This task will convert between normal uv data and compressed
       format.  Note: this should usually be done to uncalibrated,
       multi-source format data as a very few AIPS tasks cannot deal
       with compressed data.
          Compressed data has only 1 floating word for each correlator
       value rather than 3.  This means that the weights for all
       polarizations, spectral channels, and IFs are forced to be the
       same although correct weights (sigma^{-2}) would not be
       identical.
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.
  FQCENTER,..>  0 => Change frequency axis reference pixel to
                     Nchan / 2 + 1
             else => do not change reference pixel
