delete_bkg_model

Synopsis

Delete a background model

delete_bkg_model( [id, bkg_id] )

Description

The delete_bkg_model command deletes a background model from the stack.

• id - the id of the dataset; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
• bkg_id - the id of the background with the model to be deleted; default is the first background dataset

Example 1

sherpa> delete_bkg_model()
sherpa> delete_bkg_model(1)
sherpa> delete_bkg_model(1, 1)

These commands are equivalent ways of deleting the background model for the default background associated with the default source dataset.

Example 2

sherpa> delete_bkg_model(bkg_id="bkg")

Delete the model associated with the background "bkg".

Example 3

sherpa> delete_bkg_model("src", 2)

Delete the model for the second background of the dataset "src".
