MARK

        CLIC\MARK f1 f2 ...  [/ANTENNA i ][/BASELINE ij] [/RESET]

    Set the antenna or baseline mark words.

    To  decide whether data should be used, CLIC uses the logical OR  of the
    data  flag words with the corresponding mark words.  Thus data from some
    subbands  may  be [temporarily] ignored even if unflagged.  Flags may be
    relative  to  antennas  or baselines.  /ANTENNA  or  /BASELINE  must  be
    given, with antenna numbers or baseline  names  as  arguments.   Several
    antennas and baselines may be given simultaneously.  Use /ANTENNA ALL or
    /BASELINE ALL for all antennas or all baselines.

    Flag names f1 f2 ...  are  alphanumeric  codes.   Valid  codes  are sub-
    band  names  (C01  to C136, L01 to L136), DATA, POINTING, SHADOW,  TSYS,
    SATURATION and LOCK and REDU

    Use option /RESET to reset flags that were accidentally set in  the mark
    words.

    MARK with no arguments (just options)  will  list  the  MARK  words cur-
    rently  in use. See also STORE FLAG /MEMORY if you want to flag a subset
    of scans in memory.
