Variation of Azimuth Angle Distribution of EAS, With Slope of the Detector Array Plane – A Examination by Semi-Montecarlo Simulation

Abstract

The azimuth angle distribution of EAS is expected, as Cosmic Rays are isotropic. It is seen that, if the plane of the detectors is not horizontal, the azimuth angle distribution becomes non-uniform. In such cases it is necessary to make proper correction for this non-uniformity, when one attempts to use the EAS data collected in such array, for source search. An attempt is made to correlate the extent of non- uniformity with the slope of the array plane, using simulation.
