Simulation of the detection of EAS events

Simulations are built up from several components. First the cluster needs to be defined. This can be a set of real stations or imaginary detectors. Then systematic detector and station errors are generated. Next a generator for shower properties is used to determine the properties of each shower (energy and direction). Then for each detector the shower particles that hit it are selected. For each of these the actual detected signal strength and arrival times (detector effects) are determined. Then the trigger conditions are checked to see if the station triggered. If it did an event will be stored for that station. This includes a GPS timestamp and the detector observables (particle count and arrival time of first particle). Finally for each shower a ‘coincidence’ will be stored, even if it was not detected by any station. The coincidence stores the parameters of the shower.
