Source catalogs#
gammapy.catalog provides convenient access to common gamma-ray source catalogs.

For each catalog, a SourceCatalog class is provided to represent the catalog table,
and a matching SourceCatalogObject class to represent one catalog source and table row.
The main functionality provided is methods that map catalog information to
SkyModel, SpectralModel,
SpatialModel, FluxPoints and LightCurve objects.
gammapy.catalog is independent from the rest of Gammapy. The typical use cases
are to compare your results against previous results in the catalogs (e.g. overplot a spectral model),
or to create initial source models for certain energy bands and sky regions.
