set_xsxset¶
- sherpa.astro.xspec.set_xsxset(name, value)[source] [edit on github]¶
Set a X-Spec model setting.
Set variables used by X-Spec models. It is equivalent to the X-Spec
xset
command 1, but only for setting the model database settings. Seeset_xsabund
,set_xscosmo
, andset_xsxsect
for the other settings.- Parameters
See also
get_xsxset
,get_xsversion
,set_xsabund
,set_xschatter
,set_xscosmo
,set_xsxsect
Notes
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_xschatter
if 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
sherpa.astro.ui.save_all

to check.
