H.E.S.S. first public test data release


In September 2018, the H.E.S.S. Collaboration has, for the first time, released a small subset of its archival data in Flexible Image Transport System (FITS) format, an open file format widely used in astronomy. The release consists of event lists and instrument response functions for 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. It is compliant to the open format specifications developed in view of the upcoming CTA Observatory. The release is meant to support the development of open-source science tools for high-level analysis of gamma-ray data by providing access to "real" gamma-ray data in the appropriate format for the first time.
