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

Create a contour plot of the unconvolved spatial model.

Displays a contour plot of the values of the model, evaluated on the data, without any PSF kernel convolution applied. The preferences are the same as contour_model.

  • id (int or str, optional) – The data set that provides the 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_source. 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.

Return the data used by contour_source.


Return the default data set identifier.


Create one or more plot types.


Create a contour plot of the model.


Set the coordinate system to use for image analysis.


Add a PSF model to a data set.


Plot the model from the default data set:

>>> contour_source()

Compare the model without and with the PSF component, for the “img” data set:

>>> contour_model("img")
>>> contour_source("img", overcontour=True)
