# contour_kernel¶

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

Contour the kernel applied to the model of an image data set.

If the data set has no PSF applied to it, the model is displayed.

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_kernel. 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_psf_contour()

Return the data used by contour_psf.

get_default_id()

Return the default data set identifier.

contour()

Create one or more plot types.

contour_psf()

Contour the PSF applied to the model of an image data set.

sherpa.astro.ui.set_coord()

Set the coordinate system to use for image analysis.

set_psf()

Add a PSF model to a data set.
