show_model

sherpa.astro.ui.show_model(id: IdType | None = None, outfile=None, clobber=False) → None

Display the model expression used to fit a data set.

This displays the model used to fit the data set, that is, the expression set by set_model or set_source combined with any instrumental responses, together with the parameter values of the model. The show_source function displays just the source expression, without the instrumental components (if any).

Parameters:

idint, str, or None, optional

The data set. If not given then all source expressions are displayed.

outfilestr, optional

If not given the results are displayed to the screen, otherwise it is taken to be the name of the file to write the results to.

clobberbool, optional

If outfile is not None, then this flag controls whether an existing file can be overwritten (True) or if it raises an exception (False, the default setting).

Raises:

sherpa.utils.err.IOErr

If outfile already exists and clobber is False.
