## Interferometry

For cross-correlations, the data reduction is made using CLIC. The following sequence is used

    CLIC\FILE BO 'name'.IPB
    CLIC\SET PROJECT FLUX
    CLIC\FIND
    CLIC\DEVICE
    CLIC\SET BAN USB LSB
    CLIC\SET SUBBANDS C01 TO C10
    CLIC\SET X I_FREQUENCY
    CLIC\SET Y AMPLITUDE PHASE
    ! Calibrate RF passband to use DSB mode
    CLIC\FIND/PROC COR/SOUR 'Strong_Quasar'
    CLIC\PLOT
    CLIC\SOLVE RF/PL
    CLIC\FIND/PROC CORR/SOUR *
    CLIC\STORE RF
    CLIC\SET RF ON CHAN
    ! Use DSB unless gain ratio is very different from 1
    CLIC\SET BAN DSB
    CLIC\SET FLUX 'Quasar' Flux    ! Specify flux of reference quasar
    CLIC\SET FLUX 'Quasar' Flux    ! More than one allowed
    CLIC\SOLVE FLUX
    CLIC\PRINT FLUX

For pointing scans, the option /FLUX file in the command:

    CLIC\SOLVE POINTING [/PLOT] /FLUX file

processes an output file containing the same information and using the same format as the single-dish flux file created by CLASS. This file may then read directly by the FLUX program.
