- class jwst.srctype.SourceTypeStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)¶
SourceTypeStep: Selects and sets a source type based on various inputs. The source type is used in later calibrations to determine the appropriate methods to use. Input comes from either the SRCTYAPT keyword value, which is populated from user info in the APT, or the NIRSpec MSA planning tool. The source type can be also specified on the command line for exposures containing a single pre-defined target.
name (str, optional) – The name of the Step instance. Used in logging messages and in cache filenames. If not provided, one will be generated based on the class name.
parent (Step instance, optional) – The parent step of this step. Used to determine a fully-qualified name for this step, and to determine the mode in which to run this step.
config_file (str path, optional) – The path to the config file that this step was initialized with. Use to determine relative path names of other config files.
**kws (dict) – Additional parameters to set. These will be set as member variables on the new Step instance.
This is where real work happens.
- class_alias = 'srctype'¶
- spec = "\n source_type = option('POINT','EXTENDED', default=None) # user-supplied source type\n "¶
This is where real work happens. Every Step subclass has to override this method. The default behaviour is to raise a NotImplementedError exception.
