Attributes Documentation

distance_goal: fit distance goal

fixed_parameters: list of parameters fixed during fitting

max_num_fit_iterations: maximum number of fit iterations

name: name of PointingModelFitter

residual_cut: cut value for spot outlier removal

uuid: UUID of PointingModelFitter

Methods Documentation

classmethod from_config(**kwargs)

Read a PointingModelFitter configuration from either configuration file or database. Either the path of a configuration file (‘input_url’) or a database collection (‘collection’) must be provided.

Parameters:

input_url (str or Path) – path of the configuration file.
name (str) – name of the SpotExtractor (as in SkyFitter.name). When loading the configuration from file, can be set to check that the configuration with the correct name is loaded. When loading from database, is used to identify the correct database record.
uuid (str) – UUID of the camera (as in PointingCamera.uuid). When loading the configuration from file, can be set to check that the configuration with the correct UUID is loaded. When loading from database, is used to identify the correct database record.
collection (str) – name of the database collection from which configuration is read
database (str) – name of the database in which the collection is stored

Returns:

fitter

Return type:

PointingModelFitter object or None
