This Catalogue contains a complete LAGO (S0) plain simulation for the LAGO 'chi' site managed by the EPOCH institution; located in Chimborazo, Ecuador, on the -1.47 latitude, -78.82 longitude and 5000 meters in altitude. Moreover, the data was generated for the geomagnetic field corresponding to the period between 2021-10-28T00:00:00Z and 2021-10-29T00:01:43Z.

The Datasets are CORSIKA inputs and outputs, which are described in the official documentation ( https://www.iap.kit.edu/corsika/70.php ). These Datasets were generated for a flux time of 86503 seconds, following the high energy integration model QGSII, in flat array mode. The E93042003 external atmosphere file was used for this site. The zenith range used was set to [0,90] degrees. The primary integration energy range used was set to [5,1e6] GeV. The local rigidity cutoff was set to 0 GV.

The completeness of the simulation and the requirements for its storing and publishing was guaranteed by the onedataSim software ( https://github.com/lagoproject/onedataSim ), relying on the ARTI software ( https://github.com/lagoproject/arti ). A detailed description of the type and generation of the Datasets and Metadata contained in this Catalogue is in the Data Management Plan of LAGO at https://lagoproject.github.io/DMP/
