- 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 tocontour_fit
(orget_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 fromget_data_contour
andget_model_contour
in thedatacontour
andmodelcontour

a
sherpa.plot.FitContour
instance- Raises:
