list_data_ids

Synopsis

List all data set IDs in a Sherpa session.

list_data_ids()

Description

Sherpa can contain, and perform fits to, several different data sets in a single Sherpa session. This function lists all data sets in a Sherpa session, by their IDs; it accepts no arguments. The Sherpa data ID allows the user to easily reference data, model, fit, and plotting information about a data set. The ID can be a user defined string or integer.

Example

sherpa> list_data_ids()

This function returns a list of all data sets which have been loaded into a Sherpa session, by their IDs.

           sherpa> list_data_ids()
	         [1, 2, 3, '3C273_pha']
