Description
A set of eight scintillators with the reduced to (50-70)ns width of their output pulse signals is applied for determination of the arrival directions of extensive air showers which are effectively detected by the Tien Shan shower installation in the energy range between 1 and 100 PeV. Up to the present time, about ~$10^6$ shower events applicable for deducing their directional angles were collected in 2021-2023 during the ~5500h of the installation operation life time. Here, the statistical characteristics of these events are presented which confirm the functioning correctness of the electronic hardware and mathematical algorithms applied for the treatment of the initial measurement data. Further on, the newly obtained information on the angular distribution of the EAS arrival points is supposed to be used for a study of the large-scale anisotropy of the PeV cosmic rays on the celestial sphere by application of the difference method which has been earlier developed for this purpose in the LPI.
