contour_source
- sherpa.ui.contour_source(id=None, replot=False, overcontour=False, **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 tocontour_source
. The default isFalse
.overcontour (bool, optional) – If
True
then add the data to an existing plot, otherwise create a new contour plot. The default isFalse
.
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)
