show_model

sherpa.astro.ui.show_model(id=None, outfile=None, clobber=False)

Display the model expression used to fit a data set.

This displays the model used to fit the data set, that is 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
  • id (int or str, optional) – The data set. If not given then all source expressions are displayed.

  • outfile (str, 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.

  • clobber (bool, 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.
