High Energy Spectroscopic System (H.E.S.S.) Galactic Plane Survey (HGPS)

The HGPS survey was a decade-long observation program carried out by the H.E.S.S. I array of Cherenkov telescopes in Namibia from 2004 to 2013. The survey covers the Galactic plane at longitudes from “l” 250° to 65° and latitudes “|b|”<3°. The angular resolution is 0.08° (~5 arcmin) and the energy range between 0.2 and 100 TeV.

The units of the Healpix maps are cm-2 s-1.
