Features of arrival time and angle-of-incidence distributions of EAS muons

Various features and correlations of the arrival time and angle-of-incidence distributions of muons of extensive air showers (EAS) are studied by analyses based on Monte-Carlo simulations of the EAS development by use the air shower simulation code CORSIKA. Trends and dependencies of the temporal dispersion of the EAS muon component on shower size and distance from the shower core are displayed by the distribution of the arrival time and angle of incidence of the first muon, of the mean and median of the single shower distribution. Special attention is called to multi-correlations in observations at different radial distances from the shower core, which are shown to provide additional information in view of a discrimination of different EAS primaries.
