COMPRESS

 

        CLIC\COMPRESS timemax uvmax

    Compress data in the current index by averaging successive   records  in
    individual   scans.    'timemax'   is   the  maximum  averaging  time in
    seconds.  Data with baseline orientation differing by  more  'uvmax'  in
    meters  in  the  UV  plane  are  not  averaged,  as well as data flagged
    differently.

    Defaults for timemax and  uvmax  are   60   seconds   and   7.5   meters
    respectively.   An  output  file  must  have  been opened to receive the
    compressed data.

    Use command COPY rather than COMPRESS to copy the  whole  current  index
    to a new file.

    For data taken after September 1992 (new correlator), the  command  will
    only   compress   the   temporal   data  (data  header   and   continuum
    subbands), since the spectral data is already compressed to 1 record per
    scan.
