Parameterization of Cherenkov Light Lateral Distribution Function as a Function of the Zenith Angle around the Knee Region

Abstract

Cherenkov light lateral distribution function (CLLDF) simulation was fullfiled using CORSIKA code for configurations of Tunka EAS array for different zenith angles. The parameterization of the CLLDF was carried out as a function of the destance from tehe shower core in extensive air showers (EAS) and zenith angle on the basis of the CORSIKA simulation for primary proton around the knee region with the energy 3.1015 eV at different zenith angles. The parametrized CLLDF is verified in comparison with the simulation that performed using CORSIKA code for two zenith angles.
