SpectralLeakStep

class jwst.spectral_leak.spectral_leak_step.SpectralLeakStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)

Bases: JwstStep

Apply a spectral leak correction to Channel 3A of MIRI MRS data.

The MIRI MRS has a spectral leak in which 6 micron light leaks into the 12 micron channel. This step applies a correction to the 12 micron channel.

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)

Apply a spectral leak correction to MIRI MRS Channel 3A data.

Parameters:

input_dataModelContainer

Container of models containing 1-D extracted spectra

Returns:

JWST DataModel

The corrected data model. This will be the input model if the step is skipped, otherwise it will be a corrected 1D extracted spectrum that contains the MRS channel 3B range.
