fit_continuum

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)

Entry point for fitting using the fitting machinery.

Parameters:

spectrumSpectrum1D

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.

fitter_FitterMeta

The astropy fitter to use for fitting the model. Default: LevMarLSQFitter

exclude_regionslist of 2-tuples

List of regions to exclude in the fitting. Passed through to the fitmodels routine.

windowtuple of wavelengths

Start and end wavelengths used for fitting.

weightslist (NOT IMPLEMENTED YET)

List of weights to define importance of fitting regions.

Returns:

modelslist of Model

The list of models that contain the fitted model parameters.
