show_filter

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

Parameters:

• id (int or str, optional) – The data set. If not given then all data sets 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:
