    FILE Name      : Opens the input file (result from CLASS or CLIC)
    INDEX          : Compute spectral index from previous results
    PRINT          : Write out results from flux computations
    READ Iant Freq : Read data from specified antenna at frequency Freq
    SOLVE          : Compute flux of measured sources

1 FILE
        [FLUX\]FILE Name

        Define the entry file name. The entry file  can  be  produced  using
    CLASS command
        ANALYZE\PRINT FLUX/OUTPUT Name
    or using CLIC command
        CLIC\SOLVE POINTING /FLUX Name

1 INDEX
        [FLUX\]INDEX Filei Name/OUTPUT Fileo [NEW]

    Compute the spectral index (with errors bars) of the  source  Name  from
    all  the  data  available on that source in the input file Filei (result
    from FLUX\PRINT).  Write the results on the output file Fileo.

    If NEW is present, the output file is created, otherwise it is appended.


1 PRINT
        [FLUX\]PRINT [/OUTPUT File [New]]

    Print the date and information lines on the meaning of each column, then
    the  fluxes  with  error bars, the frequency, the antenna number and the
    average antenna efficiency (Jy/K), with error bars.   The  command  asks
    for  atmospheric conditions and quality of the data and writes it in the
    header of the output file.

    If NEW is present, the output file is created, otherwise it is appended.


1 READ
        [FLUX\]READ Iant Freq

        Read the gaussian fits data from the antenna  number  Iant  and  the
    frequency  Freq. The frequency must be the LSB frequency tuning given at
    +- 0.5 GHz.

1 SOLVE
        [FLUX\]SOLVE [Name1 [Name2 [...]]]

    Use the sources Name1, Name2, etc... as flux references.  For a  planet,
    the   flux   is  derived  using  the  gain  USB/LSB  and  the  frequency
    informations. For other sources, the flux specified by command SET  FLUX
    is  used.  Without  argument, all the planets included in the input file
    are used to calculate the antenna efficiency.

    The fluxes of all sources is computed as described below at  the  ``gain
    corrected'' frequency:
        F = ( F(LSB) + G x F(USB) ) / (1+G)
    where G is the USB to LSB receiver gain ratio.

    The computation steps are
       + Correct Azimuth subscan for elevation pointing error
       + Correct Elevation subscan for azimuth pointing error
       + Average both subscans to derive the source intensity
            (with proper weighting using standard deviations)
       + Average all independant scans on the same source
            (with proper weighting)
       + Determine the  average antenna efficiency from the list of
            sources of known flux, with error estimate
       + Determine the unknown fluxes, giving the error estimates:
            Relative, including only errors on the source intensity, and
            Absolute which also includes the error on antenna efficiency.
