Observation of the Moon shadow in the muon flux and its application for the calibration of the ANTARES neutrino telescope

The Sun and the Moon are expected to be obstacles for the primary cosmic rays on their way to the Earth. As a result of absorption, the effect of their deficiency and, consequently, the deficiency in the flow of atmospheric muons, measured on the Earth in the direction of the Sun and the Moon, should also arise. Detection of such a lack of events («shadow») and the determination of its position in the sky provide the ability to measure the resolving power of the particle detector and determine its orientation. The data of these measurements can be applied for its calibration. This article presents the results of analysis of data from the ANTARES detector collected during the period from 2013 to 2015.
