show_fit

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

Summarize the fit results.

Display the results of the last call to fit, including: optimization method, statistic, and details of the fit (it does not reflect any changes made after the fit, such as to the model expression or fit parameters).

Parameters:
  • 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.
