SET RF_PASSBAND

SET RF_PASSBAND

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

        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.

        SET RF_PASSBAND DOPPLER|NODOPPLER

            SET RF_PASSBAND DOPPLER enables a shift of the RF SPECTRUM  solution
            by  the difference of LO1 frequency between the solution and the ob-
            servation. SET RF_PASSBAND NODOPPLER deactivates this  option.  This
            applies only to the SET RF_PASSBAND FILE option.
