# MRSIMatchStep¶

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

MRSIMatchStep: Subtraction or equalization of sky background in MIRI MRS science images.

Create a Step 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 of other config files.

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

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