get_fit_contour

sherpa.astro.ui.get_fit_contour(id=None, recalc=True)

Return the data used by contour_fit.

Parameters

• id (int or str, optional) – The data set. If not given then the default identifier is used, as returned by get_default_id.

• recalc (bool, optional) – If False then the results from the last call to contour_fit (or get_fit_contour) are returned, otherwise the data is re-generated.

Returns

fit_data – An object representing the data used to create the plot by contour_fit. It contains the data from get_data_contour and get_model_contour in the datacontour and modelcontour attributes.

Return type

a sherpa.plot.FitContour instance

Raises

• sherpa.utils.err.DataErr – If the data set is not 2D.

• sherpa.utils.err.IdentifierErr – If the data set does not exist or a source expression has not been set.
