SCALE_FLUX

        [CALIBRATE\]SCALE_FLUX Find|Apply|List|Calibrate [Args...]

    A set of commands to check flux calibration on a day to day basis.  It gives
    the ratio between the observed flux (in the current UV  data  set)  and  the
    model  flux  for  each  separate period.  The Model flux can be derived from
    Clean Component Tables using the MODEL command, or read from an  outer  file
    using READ MODEL.

    Error  bars  are approximate. The User-defined command SOLVE_FLUX performs a
    more accurate evaluation of the error, but is typically 50 times slower.

    SCALE_FLUX FIND [DateTolerance [UVmin UVmax]]
    determines, by linear regression, the best scaling factor to match  date  by
    date  the  UV data set with the MODEL data set. Separate Periods are defined
    when Dates differ more than DateTolerance (default 1 day).  Only  data  with
    baseline  lengths in the range UVmin UVmax are considered for the regression
    (default all).

    SCALE_FLUX APPLY VarName
    apply previously determined flux scale factors to the MODEL data set, previ-
    ously read by READ MODEL. This is in  general  used  only  in  an  iterative
    search  way, e.g. by the user-defined command SOLVE_FLUX (which calls proce-
    dure solve_flux). The resulting UV data set is  loaded  into  the  specified
    VarName SIC variable.

    SCALE_FLUX LIST
    print out dates, baselines and determined flux factors

    SCALE_FLUX CALIBRATE
    apply  previously  determined  flux scale factors to the current UV data set
    (i.e. divide the visibilities by the scaling factor of each date,  and  cor-
    rect  the weight accordingly).  This may then be written using command WRITE
    UV .

    SCALE_FLUX SOLVE [DateTolerance [UVmin UVmax]]
    combines FIND and PRINT behaviours.
