Linear1D
[source] [edit on github]¶ Bases:
astropy.modeling.Fittable1DModel
One dimensional Line model.
Parameters: slope : float
Slope of the straight line
intercept : float
Intercept of the straight line
Other Parameters: fixed : a dict
A dictionary
{parameter_name: boolean}
of parameters to not be varied during fitting. True means the parameter is held fixed. Alternatively thefixed
property of a parameter may be used.tied : dict
A dictionary
{parameter_name: callable}
of parameters which are linked to some other parameter. The dictionary values are callables providing the linking relationship. Alternatively thetied
property of a parameter may be used.bounds : dict
eqcons : list
A list of functions of length
n
such thateqcons[j](x0,*args) == 0.0
in a successfully optimized problem.ineqcons : list
A list of functions of length

such thatieqcons[j](x0,*args) >= 0.0
is a successfully optimized problem.See also
