contour_kernel

sherpa.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.
