OutlierDetectionStep¶
- class jwst.outlier_detection.OutlierDetectionStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)[source]¶
Bases:
JwstStep
Flag outlier bad pixels and cosmic rays in DQ array of each input image.
Input images can be listed in an input association file or already opened with a ModelContainer. DQ arrays are modified in place.
- Parameters:
input_data (asn file or ModelContainer) – Single filename association table, or a datamodels.ModelContainer.
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.
