SET RF_PASSBAND

        CLIC\SET RF_PASSBAND [ON|OFF] [CHANNEL|FREQUENCY|SPECTRUM]
        [FILE|MEMORY] [ANTENNA|BASELINE]

    This  command  controls  the behaviour of CLIC regarding the RF passband
    calibration.

    SET RF_PASSBAND ON|OFF

        Switch ON or OFF the application of RF passband calibration curve in
        plotting the data.  The RF passband calibration curve is computed by
        SOLVE RF_PASSBAND and stored with the  data  by  STORE  RF_PASSBAND.
        Subsequent PLOT commands will use or not this curve according to the
        status of SET RF_PASSBAND ON|OFF.

    SET RF_PASSBAND CHANNEL|FREQUENCY

        Use either the channel dependent passband curves  or  the  frequency
        dependent  passband  curve.   The  channel-dependent passband curves
        must be determined separately for each subband, while the frequency-
        dependent passband curve is determined by using SOLVE RF_PASSBAND on
        all subbands together (Note: this will not work for data  taken  be-
        fore July 14th 1990). SET RF_PASSBAND FREQUENCY is recommended.

    SET RF_PASSBAND MEMORY|FILE

        Use either the passband curves just determined by SOLVE RF_PASSBAND,
        and still present in the program memory, or the passband curves pre-
        viously  stored  in  the data headers of the input file by a command
        STORE RF_PASSBAND.

    SET RF_PASSBAND ANTENNA|BASELINE

        Switch between Antenna-based and Baseline-based RF passband calibra-
        tions.  This  switch  will be active for SOLVE RF_PASSBAND (passband
        determination), STORE RF_PASSBAND (passband storing operation),  and
        SET RF_PASSBAND ON (fpassband application).  Both baseline-based and
        antenna-based calibration curves may be stored alongside in the data
        header, independently of each other. SET RF_PASSBAND ANTENNA is rec-
        ommended.

    SET RF_PASSBAND SPECTRUM

        In the MEMORY mode, will look for a SPECTRUM solution in memory (ob-
        tained  after a SOLVE RF /SPECTRUM command). In FILE mode, this will
        look for a scan stored in the hpb file. In several file are  present
        they  can  be  selected with SET RF FILE #i. Solutions can be listed
        with LIST /BANDPASS option.
