SourceCatalogStep¶
- class jwst.source_catalog.SourceCatalogStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)[source]¶
Bases:
JwstStep
Create a final catalog of source photometry and morphologies.
- Parameters:
input (str or
ImageModel
) – A FITS filename or anImageModel
of a drizzled image.
Create a
Step
instance.- Parameters:
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.
