Abstract: Arrival zenith angle distribution for the Extensive Air Showers (EAS) with a wide range of number of charged particles is studied using the experimental data obtained using the EAS 4-detector array TBS in Tbilisi. The station is a part of the GELATICA net in Georgia (GEorgian Large-area Angle and Time Coincidence Array). This experiment is devoted to the study of possible correlations in the arrival times and directions of separate EAS events over large distances and to the Primary Cosmic Ray energy spectrum investigation at very high energies. It is shown that the distribution function with the exponential dependence of showers’ flux on absorbing atmospheric depth provides a good approximation for the angular distribution despite the existing azimuth anisotropy of array. The dependence of the EAS absorption path estimation on the angular measure cutoff boundary is studied.
