DQInitStep

class liger_iris_pipeline.DQInitStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)

Bases: JwstStep

Initialize the Data Quality extension from the mask reference file.

The dq_init step initializes the pixeldq attribute of the input datamodel using the MASK reference file. For some FGS exp_types, initalize the dq attribute of the input model instead. The dq attribute of the MASK model is bitwise OR’d with the pixeldq (or dq) attribute of the input model.

Create a Step instance.

Parameters:

namestr, 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.

parentStep 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_filestr 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.

**kwsdict

Additional parameters to set. These will be set as member variables on the new Step instance.
