MINIMIZE

        FIT\MINIMIZE

    Performs  a fit of a theoretical profile in the R spectrum using initial
    values specified by the command LINES. The profile is determined by  the
    METHOD command (GAUSS, SHELL or NH3 lines are currently implemented, and
    a special method, CONTINUUM, may be used for continuum data).

    MINIMIZE performs the fit only on the part of the spectrum  selected  by
    SET  MODE  X. It also ignores the regions under the masks defined by SET
    MASK.

    If LINES is 0, an attempt to guess initial values for a single  line  is
    done  by computing the moments of the spectrum.  A first minimisation is
    performed using the Simplex technique; the results are improved and  the
    uncertainties computed using the Gradient technique. If MINIMIZE did not
    converge, the errors quoted in the  results  are  meaningless,  and  you
    should use command ITERATE to try to do better.

    For  CONTINUUM  method,  although  a  linear baseline is fitted with the
    gaussian, only the gaussian parameters are displayed.  If  the  observa-
    tion was made using beam-switching method and the reference beam appears
    in the drifts, a two-component gauss fit is done using separation speci-
    fied in the data.
