  New results of 300 hours of operation of the Tunka array are presented.
  An improved parametrization of the Cherenkov light lateral distribution
function (LDF), based on CORSIKA Monte Carlo simulations and the experiment
QUEST, has been used for the reconstruction of EAS parameters. The corrected
energy spectrum in the knee region is obtained. The mean depth of the EAS
maximum has been derived both from the analysis of LDF steepness and the FWHM
of Cerenkov light pulse. The mean mass composition around the knee is
estimated.
