The dataset consists of 10% of all the events recorded by the Pierre Auger Observatory that pass high-level quality selection checks (explained below). The periods of data recording are: from January 2004 to August 2018 for the SD1500 events; from December 2004 to December 2017 for the hybrid events (SD1500 & FD); from January 2014 to August 2018 for the SD750 events and for the hybrid events involving the HEAT-Coihueco telescopes.
- SD-1500 m array with theta < 60⁰ for energies exceeding 3 EeV
- SD-1500 m array with 60⁰ < theta < 80⁰ for energies exceeding 4 EeV
- SD-750 m array with theta < 40⁰ for energies exceeding 0.8 EeV
- Golden hybrid data with theta < 60⁰ (both FD and SD reconstruction)
