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.
