Synopsis
Reset the model parameters to their default settings.
Syntax
reset(model=None, id=None)
Description
The `reset` function restores the parameter values to the default value set by `guess` or to the user-defined default. If the user set initial model values or soft limits - e.g. either with `set_par` or by using parameter prompting via `paramprompt` - then `reset` will restore these values and limits even after `guess` or `fit` has been called.
Examples
Example 1
The following examples assume that the source model has been set using:
>>> set_source(powlaw1d.pl * xsphabs.gal)
Example 2
Fit the model and then reset the values of both components ( pl and gal ):
>>> fit() >>> reset()
Example 3
Reset just the parameters of the pl model component:
>>> reset(pl)
Example 4
Reset all the components of the source expression for data set 2.
>>> reset(get_source(2))
PARAMETERS
The parameters for this function are:
| Parameter | Type information | Definition |
|---|---|---|
| model | optional | The model component or expression to reset. The default is to use all source expressions. |
| id | int, str, or None, optional | The data set to use. The default is to use all data sets with a source expression. |
