Methods Documentation

components_models(which='best', linked=False)[source]#

Models of the source components.

Parameters:
which{‘best’, ‘pl’, ‘ecpl’}

Which spectral model.

linkedbool

Each subcomponent of a source is given as a different SkyModel. If True, the spectral parameters except the normalisation are linked. Default is False.

Returns:
sky_modelModels

Models of the catalog object.

info(info='all')[source]#

Information string.

Parameters:
info{‘all’, ‘basic’, ‘map’, ‘spec’, ‘flux_points’, ‘components’, ‘associations’, ‘id’}

Comma separated list of options.

sky_model(which='best')[source]#

Source sky model.

Parameters:
which{‘best’, ‘pl’, ‘ecpl’}

Which spectral model.

Returns:
sky_modelModels

Models of the catalog object.

spatial_model()[source]#

Spatial model as a SpatialModel object.

One of the following models (given by Spatial_Model in the catalog):

spectral_model(which='best')[source]#

Spectral model as a SpectralModel object.

One of the following models (given by Spectral_Model in the catalog):

Parameters:
which{‘best’, ‘pl’, ‘ecpl’}

Which spectral model.
