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

Display the results of the last covar evaluation.

The output includes the best-fit model parameter values, associated confidence limits, choice of statistic, and details on the best fit location.

  • 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).


sherpa.utils.err.IOErr – If outfile already exists and clobber is False.
