hess_drH.E.S.S. DL3 DR1 - Public Test Data Release 1 The release consists of event lists and instrument response functions
(Data Level 3 products) for H.E.S.S. observations of various
well-known gamma-ray sources (the Crab nebula, PKS 2155-304, MSH
15-52, RX J1713.7-3946) as well as observations of empty fields for
background modeling.
