MASK

            CLIC\MASK f1 f2 ...  [/ANTENNA i1 [...]] [/BASELINE  b1 [...]]
            [/RESET] [/ALL] [/SPECTRAL]

        This command causes some flags to be ignored by setting the  antenna  or
        baseline  "mask"  words.  Data flagged will normally not be processed by
        calibration commands. However flags set in the corresponding  mask  word
        will be ignored, causing data to be processed anyway. Flags may be rela-
        tive to antennas or baselines. One of the options /ANTENNA or  /BASELINE
        must therefore be given, with antenna numbers or baseline names as argu-
        ments.

        Supported flag names are:

        - C001 to C136 for bad individual continuum correlator subbands
        - L001 to L136 for bad individual spectral correlator subbands
        - DATA for bad data
        - TSYS for too high system temperature (antenna based only)
        - LOCK for out of lock local oscillator (antenna based only)
        - POINTING for poor pointing (antenna based only)
        - SHADOW for antenna being shadowed by another antenna (ant. based only)
        - SATURATION for too high total power on a particular antenna
        - TIME for time discontinuity
        - DOPPLER for doppler discontinuity
        - REDU for data reduction

        Option /ALL will mask all flags.

        Option /SPECTRAL will mask the spectral flag (C001 to C136 and  L001  to
        L136)

        Use option /RESET to remove flags from the mask works.

        MASK with no arguments will list the mask words currently in use.
