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.
