PathLossStep
(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)[source]¶ Bases:
jwst.stpipe.Step
PathLossStep: Inserts the pathloss and wavelength arrays into the data.
Pathloss depends on the centering of the source in the aperture if the source is a point source. This step fills the following attributes in the datamodel:
- for exposure type
NRS_IFU
, the 1-d arrays .wavelength_pointsource, .pathloss_pointsource, .wavelength_uniformsource and .pathloss_uniformsource - for exposure types NRS_FIXEDSLIT, NRS_BRIGHTOBJ, and NRS_MSASPEC, the 1-d arrays .slits[n].wavelength_pointsource, .slits[n].pathloss_pointsource, .slits[n].wavelength_uniformsource and .slits[n].pathloss_uniformsource
In all of these
EXP_TYPES
, these arrays are added to each member of theslits

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.
- **kws (dict) – Additional parameters to set. These will be set as member variables on the new Step instance.
