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:

  • 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 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.

  • **kws (dict) – 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_data (str, 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_spectrum – A single combined 1D spectrum.

Return type:

MultiCombinedSpecModel
