Catalog of the Highest-Energy Cosmic Rays recorded during Phase I of Operation of the Pierre Auger Observatory

   Catalog dataset

The Catalog consists of a data set of 109 showers measured with the array of water-Cherenkov detectors. In 10 of these there were also measurements made with the fluorescence detector (hybrid events). These data are available as two summary CSV files containing the reconstructed shower parameters, one relating to all 109 events, and another to the 10 hybrid ones.
The information contained in each summary files are:
