The distribution of the arrival zenith angle Extensive Air Showers (EAS) with a wide range total number charged particles is studied using experimental data obtained EAS 4-detector array 'TSU' in Tbilisi. station part GELATICA net Georgia (GEorgian Large-area Angle and TIme Coincidence Array), which devoted to study possible correlations times directions separate events over large distances. It shown that function conventional exponential dependence showers' flux on absorbing air thickness provides good approximation for direction distribution. absorption path estimation angular trimming boundary set studied; necessity strict verification used value stated.
