SET AMPLITUDE

            CLIC\SET AMPLITUDE [ABSOLUTE|RELATIVE] [SCALED|UNSCALED]
            [KELVIN|JANSKY] [ANTENNA|BASELINE] [RAW] [SIZED|UNSIZED]
            [SPIDX|NOSPIDX]

        This command controls which scaling factor is applied to  the  data  for
        plotting  and  writing in the output table, in subsequent PLOT and TABLE
        commands:

          - ABSOLUTE means that the relative amplitude calibration  is  not  ap-
            plied.

          -  RELATIVE  means  that the relative amplitude calibration, as deter-
            mined with SOLVE AMPLITUDE, and stored with STORE AMPLITUDE, is  ap-
            plied.

          -  SCALED  means  that the absolute amplitude is divided by the source
            flux; SCALED is only used for the command SOLVE AMPLITUDE.

          - KELVIN|JANSKY indicates the unit in which  the  amplitude  are  dis-
            played: either Kelvins (in main-beam brightness temperature) or Jan-
            skys.

        SET AMPLITUDE ABSOLUTE forces SET AMPLITUDE KELVIN since the uncalibrat-
        ed data are measured in Kelvins. With SET AMPLITUDE RELATIVE, the ampli-
        tudes are in Janskys, since a calibrator of known flux has been used for
        reference.  If  the default is overridden (SET AMPLITUDE ABSOLUTE JANSKY
        or SET AMPLITUDE RELATIVE KELVIN), conversion  factors  (=antenna  effi-
        ciencies)  are  taken from the scan headers; these factors may be deter-
        mined by SOLVE FLUX and stored by STORE FLUX.

        SET AMPLITUDE ANTENNA|BASELINE switches between Antenna-based and  Base-
        line-based amplitude calibrations.  This switch will be active for SOLVE
        AMPLITUDE (calibration curve determination), STORE  AMPLITUDE  (calibra-
        tion curve storing operation), and SET AMPLITUDE RELATIVE (application).
        Both baseline-based and antenna-based calibration curves may  be  stored
        alongside in the data header, independently of each other. Using SET AM-
        PLITUDE ANTENNA is recommended.

        SET AMPLITUDE RAW allows to plot the amplitude  as  correlation  coeffi-
        cient  by  dividing  the amplitudes by the geometrical average of system
        temperatures of the antennas consisting the considered baseline.

        SET AMPLITUDE SIZED|UNSIZED switches on and off a correction of the  am-
        plitude for source size (sources with known size are W3OH and MWC349).

        SET  AMPLITUDE SPIDX|NOSPIDX switches on and off a correction of the am-
        plitude for the source spectral index (w.r.t. the reference frequency).
