gammapy.catalog.SourceCatalog2HWC(filename='$GAMMAPY_DATA/catalogs/2HWC.ecsv')[source]¶ Bases:
gammapy.catalog.SourceCatalogHAWC 2HWC catalog.
One source is represented by
SourceCatalogObject2HWC.The data is from tables 2 and 3 in the paper [R765ffce297c8-1].
The catalog table contains 40 rows / sources. The paper mentions 39 sources e.g. in the abstract. The difference is due to Geminga, which was detected as two “sources” by the algorithm used to make the catalog, but then in the discussion considered as one source.
