Overview

The corrected dependence of the mean depth of the EAS maximum \\(X_{max}\\) on the energy was obtained from the data of the Tunka-133 array for 7 years and the TAIGA-HiSCORE array for 2 years. The parameter \\(\\langle\\ln A\\rangle\\), characterizing the mean mass compositon was derived from these results. The differential energy spectrum of primary cosmic rays in the energy range of \\(2\\cdot 10^{14}\\) - \\(2\\cdot 10^{16}\\)\\,eV was reconstructed using the new parameter \\(Q_{100}\\) the Cherenkov light flux at the core distance 100 m.}
