Synopsis
Delete the background model expression for a data set.
Syntax
delete_bkg_model(id=None, bkg_id=None)
Description
This removes the model expression, created by `set_bkg_model` , for the background component of a data set. It does not delete the components of the expression, or remove the models for any other background components or the source of the data set.
Examples
Example 1
Remove the background model expression for the default data set:
>>> delete_bkg_model()
Example 2
Remove the model expression for the background component labelled 'down' for the data set with the identifier 'src':
>>> delete_bkg_model('src', 'down')PARAMETERS
The parameters for this function are:
| Parameter | Type information | Definition |
|---|---|---|
| id | int, str, or None, optional | The data set containing the source expression. If not given then the default identifier is used, as returned by `get_default_id` . |
| bkg_id | int, str, or None, optional | The identifier for the background component to use. |
