Abstract
The methodical problems related to analysis of the zenith-angle distribution of extensive air showers with N e > 107 particles are discussed. The effect of the array geometry on the angle measurement error is considered. Possible distortions of angular distribution due to errors have been calculated. The presence of excess showers detected at large zenith angles is shown.
