2022-12-12T10:25:17Z 100 HESS Public Test Release 1 High Energy Stereoscopic System (H.E.S.S.) is a system of imaging atmospheric Cherenkov telescopes (IACTs) for the investigation of cosmic gamma rays in the photon energy range of 80 GeV to 100 TeV. The data published here is a list of estimated parameters of gamma-ray candidates, i.e. particles for which it was determined with a high likelihood that they are not cosmic-ray background, but gamma rays. The provided parameters are: * incoming direction as position in the sky * energy * likelihood of being a gamma ray * run number The data are taken in runs of 28 minutes. For each run, the data of all auxiliary systems are recorded and links to air shower simulations and lookup tables corresponsing to the environment and state of the instrument are provided. high-energy-astrophysics gamma-ray-astronomy particle-astrophysics HESS collaboration H.E.S.S.

The data and documentation is publicly released by the H.E.S.S. collaboration as a contribution to the ongoing efforts to define a common open format for data level 3 of imaging atmospheric Cherenkov telescopes (IACTs) and IACT open-source science tool development, to enlarge the community involved in IACT data analysis. No scientific publications may be derived from the data. Using the data for new claims about the astrophysical sources is not permitted.

H.E.S.S. observes in bunches of 18 minutes, and each bunch is characterised by some metadata.
