Combine1dStep

class jwst.combine_1d.Combine1dStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)[source]

Bases: JwstStep

Combine 1D spectra.

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]

Combine the input data.

Parameters:
input_datastr, ModelContainer, MultiSpecModel, TSOMultiSpecModel, MRSMultiSpecModel

Input is expected to be an association file name, ModelContainer, or multi-spectrum model containing multiple spectra to be combined. Individual members of the association or container are expected to be multi-spectrum model instances.

Returns:
output_spectrumMultiCombinedSpecModel

A single combined 1D spectrum.
