Based on this simulation, sets of estimated functions for elementary protons and iron, carbon and helium nuclei were generated at azimuth angles of 30 and 40°. By comparing the predicted lateral distribution function of Cherenkov radiation with all data obtained using the Chacaltaya system, the ability to determine the principal particles and energy around the "knee" region was demonstrated.
