10-100 TeV cosmic ray anisotropy measured at Baksan EAS "Carpet" array

TL;DR

This paper reports on the measurement of cosmic ray anisotropy in the 10-100 TeV energy range using the Baksan EAS array, comparing two analysis methods and analyzing amplitude and phase variations with energy.

Contribution

It introduces a comparative analysis of anisotropy measurement methods and provides new data on amplitude and phase at multiple energies in the 10-100 TeV range.

Findings

Anisotropy amplitudes and phases are reported at 25, 75, and 120 TeV.

Comparison of standard and East-West methods shows consistent results.

Amplitude-phase dependence on energy is briefly discussed.

Abstract

Preliminary results of one year anisotropy measurement in the energy range 10^{13} -10^{14} eV as a function of energy are presented. The results are compared for two methods of data analysis: the standard one with meteo correction approach in use and another one so-called "East minus West" method. Amplitudes and phases of anisotropy for three median energies E = 25 TeV, E = 75 TeV and E = 120 TeV are reported. Brief consideration of amplitude-phase dependence of anisotropy on energy is expounded.
