    ITERATE  tries the GRADIENT technique to improve the last results of the
    profile fit. Optional argument N indicates the number of iterations.  Do
    not expect spectacular results if the absolute minimum is far away! Typ-
    ically, this command should be used if the previous  fit  did  not  con-
    verge,  but  seems  close enough.  If you are using the GAUSS method, be
    cautious not to change the X unit in the mean time.
