show_source

Context: info

Syntax

show_source([id, outfile=None, clobber=False] )

Description

The show_source command displays the unconvolved source model. To obtain the convolved model information, use the command show_model ("ahelp show_model").

id - the id of the dataset to use; default is to show source information for all available datasets.
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:

Model: 1
(xsphabs.abs1 * powlaw1d.p1)

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_source()

Print the source information for all datasets to the screen.

Example 2

sherpa> show_source(2, "sherpa.source", True)

Write the source information for dataset id=2 to the file "sherpa.source", clobbering any existing file with the same name.
