The Amplitude Calibrator is too weak for Pointings

In this case, only the cross-correlations are used. Don't forget to apply the SOLVE FLUX command only on a short time interval where the weather conditions: H$_2$O vapor contents and phase noise are quite similar.

   - Select the RF bandpass done usually after a FOCUS and a POINTING 
   - Select the adjacent Phase Calibrator(s)- it should follow a POINTING

        CLIC\SET RF ON FREQ
        CLIC\SET PHASE RELATIVE
        CLIC\SET BAND DSB
        CLIC\SET SUB L01 TO L06
        CLIC\SET SOURCE Phase_Calib RF_Calib
        CLIC\SET FLUX RF_Calib xx.x     !see flux reports
        CLIC\SET PROC CORR
        CLIC\FIND /SCAN x y     !After a pointing on RF_Calib
        CLIC\FIND APPEND /SCAN v w      !After a pointing on Phase_Calib
        CLIC\SOLVE FLUX

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'').
