contour_fit_resid

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

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, str, or None, 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 existing plot, otherwise create a new contour plot. The default is False.
