delete_model

Context: modeling

Synopsis

Delete a Sherpa model by model ID

Syntax

delete_model( [id] )

Description

The delete_model() function removes a specified model from the list of active models in a Sherpa session, by model ID; the model ID is the same as the ID of the data set to which it is assigned.

id - the id of the data set to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")

Example 1

sherpa> delete_model()

When called with no arguments, delete_model() removes from the Sherpa session the model assigned to the default data set.
