      abstract     = {The Tunka Advanced Instrument for Gamma- and cosmic-ray
                      Astronomy (TAIGA) is a multicomponent experiment for the
                      measurement of TeV to PeV gamma- and cosmic rays. Our goal
                      is to establish a novel hybrid direct air shower technique,
                      sufficient to access the energy domain of the long-sought
                      Pevatrons. The hybrid air Cherenkov light detection
                      technique combines the strengths of the HiSCORE shower front
                      sampling array, and two $\thicksim$4 m class, $\sim$9.6 deg
                      field of view Imaging Air Cherenkov Telescopes (IACTs). The
                      HiSCORE array provides good angular and shower core position
                      resolution, while the IACTs provide the image shape and
                      orientation for gamma-hadron separation. In future, an
                      additional muon detector will be used for hadron tagging at
                      $\ge$ 100 TeV energies. Here, only data from the first IACT
                      of the TAIGA experiment are used. A random forest algorithm
                      was trained using Monte Carlo (MC) simulations and real
                      data, and applied to 85 h of selected observational data
                      tracking the Crab Nebula at a mean zenith angle of 33.5 deg,
                      resulting in a threshold energy of 6 TeV for this dataset.
                      The analysis was performed using the gammapy package. A
                      total of 163.5 excess events were detected, with a
                      statistical significance of 8.5 sigma. The observed spectrum
                      of the Crab Nebula is best fit with a power law above 6 TeV
                      with a flux normalisation of $(3.20\pm0.42)\cdot10^{-10}
                      TeV^{-1} cm^{-2} s^{-1})$ at a reference energy of 13 TeV
                      and a spectral index of $-2.74\pm0.16$.},
