specutils.fitting.fit_continuum(spectrum, model=<Chebyshev1D(3, c0=0., c1=0., c2=0., c3=0.)>, fitter=<astropy.modeling.fitting.LevMarLSQFitter object>, exclude_regions=None, window=None, weights=None)[source]

Entry point for fitting using the fitting machinery.

Parameters:

spectrum : Spectrum1D

The spectrum object overwhich the equivalent width will be calculated.

model: list of `~astropy.modeling.Model`

The list of models that contain the initial guess.

fitmodels_type: str

String representation of fit method to use as defined by the dict fitmodels_types.

window : tuple of wavelengths (NOT IMPLEMENTED YET)

Start and end wavelengths used for fitting.

weights : list (NOT IMPLEMENTED YET)

List of weights to define importance of fitting regions.
Returns:

models : list of Model

The list of models that contain the fitted model parmeters.
