Abstract

The corrected dependence of the mean depth of the EAS maximum Xmax on the energy was obtained from the data of the Tunka-133 array for 7 years and the TAIGA-HiSCORE array for 2 year. The parameter 〈lnA〉, characterizing the mean mass compositon was derived from these results. The differential energy spectrum of primary cosmic rays in the energy range of 2 · 1014 – 2 · 1016 eV was reconstructed using the new parameter Q100 the Cherenkov light flux at the core distance 100 m.
