contour_source

sherpa.astro.ui.contour_source(id=None, **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.

Parameters
  • 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 exsiting plot, otherwise create a new contour plot. The default is False.

See also

get_source_contour()

Return the data used by contour_source.

get_default_id()

Return the default data set identifier.

contour()

Create one or more plot types.

contour_model()

Create a contour plot of the model.

sherpa.astro.ui.set_coord()

Set the coordinate system to use for image analysis.

set_psf()

Add a PSF model to a data set.

Examples

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)
