- sherpa.astro.xspec.set_xsxset(name, value)
Set a X-Spec model setting.
Set variables used by X-Spec models. It is equivalent to the X-Spec
xsetcommand 1, but only for setting the model database settings. See
set_xsxsectfor the other settings.
The available settings are listed at 1. Not all the X-Spec model types are supported by Sherpa - for instance X-Spec “mixing models” - so changing some of these settings will make no difference. The X-Spec chatter setting can be increased with
set_xschatterif it is not clear if a setting is being used.
The model settings are stored so that they can be included in the output of
