get_iter_method_opt
(optname=None)¶ 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: dictionary or value Raises: sherpa.utils.err.ArgumentErr
– If theoptname
argument is not recognized.See also
get_iter_method_name()
- Return the name of the iterative fitting scheme.
set_iter_method_opt()
- Set an option for the iterative-fitting scheme.
set_iter_method()
- Set the iterative-fitting scheme used in the fit.
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')
