# contour_fit_resid¶

sherpa.astro.ui.contour_fit_resid(id=None, replot=False, overcontour=False, **kwargs)

Contour the fit and the residuals to a data set.

Overplot the model - including any PSF - on the data. In a separate plot contour the residuals. The preferences are the same as contour_data and contour_model.

Parameters: id (int or str, optional) – The data set that provides the data and model. If not given then the default identifier is used, as returned by get_default_id. replot (bool, optional) – Set to True to use the values calculated by the last call to contour_fit_resid. The default is False. overcontour (bool, optional) – If True then add the data to an exsiting plot, otherwise create a new contour plot. The default is False.

get_fit_contour()
Return the data used by contour_fit.
get_default_id()
Return the default data set identifier.
contour()
Create one or more plot types.
contour_fit()
Contour the fit to a data set.
contour_resid()
Contour the residuals of the fit.
sherpa.astro.ui.set_coord()
Set the coordinate system to use for image analysis.

Examples

Plot the fit and residuals for the default data set:
