Table information for 'hess_dr.vo_obscore'


Table Description: ObsCore description of event lists for observations in the H.E.S.S. DL3 public test data release 1

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: 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.
