PhotomStep

class jwst.photom.PhotomStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)[source]

Bases: JwstStep

Apply photometric calibration.

Create a Step instance.

Parameters:

namestr: 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.
parentStep: 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_filestr or pathlib.Path: The path to the config file that this step was initialized with. Use to determine relative path names of other config files.
_validate_kwdsbool: Validate given kws against specs/config.
**kwsdict: Additional parameters to set. These will be set as member variables on the new Step instance.

Methods Documentation

process(input_data)[source]

Execute the photom calibration step.

This step loads photometric conversion information from reference files and attaches or applies them to the input science data model.

Parameters:

input_datastr: Input science data file to be calibrated

Returns:

resultDataModel: DataModel with the photom correction applied
