    Other Parameters
    ----------------
    fixed : a dict, optional
        A dictionary ``{parameter_name: boolean}`` of parameters to not be
        varied during fitting. True means the parameter is held fixed.
        Alternatively the `~astropy.modeling.Parameter.fixed`
        property of a parameter may be used.
    tied : dict, optional
        A dictionary ``{parameter_name: callable}`` of parameters which are
        linked to some other parameter. The dictionary values are callables
        providing the linking relationship.  Alternatively the
        `~astropy.modeling.Parameter.tied` property of a parameter
        may be used.
    bounds : dict, optional
        A dictionary ``{parameter_name: value}`` of lower and upper bounds of
        parameters. Keys are parameter names. Values are a list or a tuple
        of length 2 giving the desired range for the parameter.
        Alternatively, the
        `~astropy.modeling.Parameter.min` and
        `~astropy.modeling.Parameter.max` properties of a parameter
        may be used.
    eqcons : list, optional
        A list of functions of length ``n`` such that ``eqcons[j](x0,*args) ==
        0.0`` in a successfully optimized problem.
    ineqcons : list, optional
        A list of functions of length ``n`` such that ``ieqcons[j](x0,*args) >=
        0.0`` is a successfully optimized problem.
