class jwst.pathloss.PathLossStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)[source]

Bases: JwstStep

PathLossStep: Apply the path loss correction to a science exposure.

Pathloss depends on the centering of the source in the aperture if the source is a point source.

Create a Step instance.

  • 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 or pathlib.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.

Methods Documentation


This is where real work happens. Every Step subclass has to override this method. The default behaviour is to raise a NotImplementedError exception.
