get_source_contour
- sherpa.astro.ui.get_source_contour(id=None, recalc=True)
Return the data used by contour_source.
- 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 tocontour_source
(orget_source_contour
) are returned, otherwise the data is re-generated.
- Returns:
source_data – The
y
attribute contains the model values and thex0
andx1
arrays contain the corresponding coordinate values, as one-dimensional arrays.- Return type:
a
sherpa.plot.SourceContour
instance- Raises:
sherpa.utils.err.DataErr – If the data set is not 2D.
sherpa.utils.err.IdentifierErr – If the data set does not exist or a source expression has not been set.
