The Amplitude Calibrator is used for Pointings

In this case, the flux of the amplitude calibrator will be determined from pointings using the RF bandpass calibrator. The method is the same as described in section 3. After doing standard RF and phase calibration, one need to reduce the pointing data and write the results in a file. The sequence is the following:

        CLIC\SET RF ON FREQ
        CLIC\SET PHASE RELATIVE
        CLIC\SET BAND DSB
        CLIC\SET SUB C01 TO C06
        CLIC\SET SOURCE Phase_Calib RF_CAlib
        CLIC\SET PROC POINT
        CLIC\FIND
        CLIC\SOLVE POINTING/[PLOT]/OUTPUT flux.fit FLUX NEW
        CLIC\EXIT

The command

CLIC\SOLVE POINTING [/PLOT] /OUTPUT file FLUX NEW[OLD]

processes an output file which can be directly read by the language FLUX in ASTRO. The section 5 explains how to use this file to derive the flux density of the amplitude calibrator using the flux of the Primary calibrator (which is given in the flux reports).

When the flux density of the amplitude calibrator is known, update the CLIC calibration procedure (described in the ``Calibration Cookbook'') as follows:

        CLIC\SET SOURCE Phase_Calib RF_CAlib
        CLIC\SET PROC POINT CORR
        CLIC\SET FLUX Phase_Calib xx.x
        CLIC\SET FLUX RF_Calib yy.y
        CLIC\FIND 
        CLIC\STORE FLUX (On all cross-correlations)

Now you can proceed to the standard Amplitude Calibration using cross-correlations on the Amplitude Calibrator (see ``Calibration Cookbook'').
