PixelReplaceStep

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

Bases: JwstStep

Replace flagged bad pixels prior to spectral extraction.

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.

process(input_data)[source]

Execute the step.

Parameters:

input_datadatamodel, str: The input datamodel or filename containing spectral data in need of pixel replacement.

Returns:

JWST DataModel: This will be input if the step was skipped; otherwise, it will be a model containing data arrays with estimated fluxes for any bad pixels, now flagged as TO-BE-DETERMINED (DQ bit 7?).
