show_covar

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.

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.

Notes

When outfile is None, the text is displayed via an external program to support paging of the information. The program used is determined by the PAGER environment variable. If PAGER is not found then ‘/usr/bin/more’ is used.
