# contour_fit¶

sherpa.astro.ui.contour_fit(id=None, **kwargs)

Contour the fit to a data set.

Overplot the model - including any PSF - on the data. 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. 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.

sherpa.astro.ui.set_coord()

Set the coordinate system to use for image analysis.

Examples

Plot the fit for the default data set:

>>> contour_fit()


Overplot the fit to data set ‘s2’ on that of the default data set:

>>> contour_fit()
>>> contour_fit('s2', overcontour=True)
