catalog - Source catalogs¶
Introduction¶
gammapy.catalog
provides convenient access to common gamma-ray source catalogs.
hgps
/SourceCatalogHGPS
- H.E.S.S. Galactic plane survey (HGPS)gamma-cat
/SourceCatalogGammaCat
- An open catalog of gamma-ray sources3fgl
/SourceCatalog3FGL
- LAT 4-year point source catalog4fgl
/SourceCatalog4FGL
- LAT 8-year point source catalog2fhl
/SourceCatalog2FHL
- LAT second high-energy source catalog3fhl
/SourceCatalog3FHL
- LAT third high-energy source catalog2hwc
/SourceCatalog2HWC
- 2HWC catalog from the HAWC observatory
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.
