get_iter_method_opt
- sherpa.astro.ui.get_iter_method_opt(optname: str | None = None) Any
Return one or all options for the iterative-fitting scheme.
The options available for the iterative-fitting methods are described in
set_iter_method_opt
.- Parameters:
optname (str, optional) – If not given, a dictionary of all the options are returned. When given, the individual value is returned.
- Returns:
value – The dictionary is empty when no iterative scheme is being used.
- Return type:

get_iter_method_name
Return the name of the iterative fitting scheme.

Set an option for the iterative-fitting scheme.
set_iter_method

Examples
Display the settings of the current iterative-fitting method:
>>> print(get_iter_method_opt())
Switch to the sigmarej scheme and find out the current settings:
>>> set_iter_method('sigmarej') >>> opts = get_iter_method_opt()
Return the ‘maxiters’ setting (if applicable):
>>> get_iter_method_opt('maxiters')
