analysis.defaults module¶
Some of the defaults that are used in the overall program.
-
analysis.defaults.
getInitialValuesFit
(g_parameters)[source]¶ Return a dictionary containing the initial values to be used in the in the fitting of the parameters.
The dictionary is of the form: ‘parameter_name:initial_value’
Args: g_parameters(
analysis.galfun.GParameters
): An object containing differentforms of the galaxy parameters.Returns: A dict.
-
analysis.defaults.
getMaximums
(g_parameters, gal_image)[source]¶ Return a dictionary containing the minimum values to be used in the in the fitting of the parameters.
The dictionary is of the form: ‘parameter_name:maximum_value’
Args: g_parameters(
galfun.GParameters
): An object containing differentforms of the galaxy parameters.Returns: A dict.
-
analysis.defaults.
getMinimums
(g_parameters, gal_image)[source]¶ Return a dictionary containing the minimum values to be used in the in the fitting of the parameters.
The dictionary is of the form: ‘parameter_name:initial_value’
Args: g_parameters(
analysis.galfun.GParameters
): An object containing differentforms of the galaxy parameters.Returns: A dict.
-
analysis.defaults.
getSteps
(g_parameters, image_renderer)[source]¶ Return a dictionary containing the steps to be used in the derivatives of each parameter.
The dictionary is of the form: ‘parameter_name:value_of_step’
Some parameter variations were copied from David’s code suggestions.
Args: g_parameters(
analysis.galfun.GParameters
): An object containing differentforms of the galaxy parameters.Returns: A dict.
