get_default_id

Synopsis

Return the default data set ID in a Sherpa session.

get_default_id()

Description

Sherpa can contain, and perform fits to, several different data sets in a single Sherpa session. The get_default_id() function returns the ID of the default data set in a Sherpa session (id=1 by default). The get_default_id() function accepts no arguments.

Example

sherpa> get_default_id()

The get_default_id() function accepts no arguments; it returns the ID of the default dataset defined for the Sherpa session.
