show_stat

Synopsis

Display the fit statistic

show_stat([outfile=None, clobber=False] )

Description

The show_stat command displays the current fit statistic.

• outfile - name of the file in which to store the information
• clobber - a Boolean switch which indicates whether or not the 'outfile' should be overwritten, if the file already exists; default=False

The command output looks like:

Statistic: CStat

The behavior of the screen output is determined by the user's $PAGER environment variable setting, which is usually a variant of "more." To disable paging within show_all() - i.e. print the entire contents, even if it scrolls offscreen - change this setting to "cat" before starting Sherpa:

unix% setenv PAGER cat

unix% sherpa

Example 1

sherpa> show_stat()

Print the statistic to the screen.

Example 2

sherpa> show_stat("sherpa.stat", True)

Write the fit statistic value to the file "sherpa.stat", clobbering any existing file with the same name.
