Abstract

The corrected dependence of the mean depth of the EAS maximum

X_{max}

Xmax 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

⟩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\cdot 10^{14}

2⋅1014 –

2\cdot 10^{16}

2⋅1016 eV was reconstructed using the new parameter

Q_{100}

Q100 the Cherenkov light flux at the core distance 100 m. Change of the parameter for the energy reconstuction for the TAIGA-HiSCORE from

Q_{200}

Q200 to

Q_{100}

Q100 provides a decreasing energy threshold for the spectrum to about 200 TeV.
