The AUGERHIT Option of the Air Shower Simulation Program CORSIKA

This report describes the size reduction of the particle data output file(s) for Auger simulations. This reduction is achieved by a (random) selection of the shower core position relative to the triangular grid of detectors, as for all shower particles in the observation plane it is checked whether they arrive in the neighbourhood of a corresponding detector position. Only hitting particles are kept for the output. All other particles falling onto the Argentinian pampa far from any detector are skipped.
