sherpa.astro.ui.
get_kernel_contour
(id=None, recalc=True)¶ Return the data used by contour_kernel.
- Parameters
id (int or str, optional) – The data set. If not given then the default identifier is used, as returned by get_default_id.
recalc (bool, optional) – If
False
then the results from the last call to contour_kernel (or get_kernel_contour) are returned, otherwise the data is re-generated.
- Returns
psf_data
- Return type
a sherpa.plot.PSFKernelContour instance
- Raises
sherpa.utils.err.DataErr – If the data set is not 2D.
sherpa.utils.err.IdentifierErr – If a PSF model has not been created for the data set.
