info(self, info='all')

Summary info string.

Parameters

info{‘all’, ‘basic’, ‘position’, ‘spectrum’}

Comma separated list of options

sky_model(self, which='point')

Sky model (SkyModel).

• which="point" - Sky model for point source analysis

• which="extended" - Sky model for extended source analysis. Only available for some sources. Raise ValueError if not available.

According to the paper, the radius of the extended source model is only a rough estimate of the source size, based on the residual excess..

spatial_model(self, which='point')

Spatial model (SpatialModel).

• which="point" - PointSpatialModel

• which="extended" - DiskSpatialModel. Only available for some sources. Raise ValueError if not available.

spectral_model(self, which='point')

Spectral model (PowerLawSpectralModel).

• which="point" – Spectral model under the point source assumption.

• which="extended" – Spectral model under the extended source assumption. Only available for some sources. Raise ValueError if not available.
