Beschreibungen/Notizen

• The results of observations of the Crab Nebula by the second HEGRA imaging atmospheric Cherenkov telescope during the period 1994/1995 are presented. The signal, detected at a level of 10 σ, allows one to estimate the flux and the spectral index of the γ-ray energy spectrum above 1 TeV. The analysis, based on the comparison of measurements with comprehensive Monte Carlo simulations, reveals a γ-ray flux F γ (≥ 1 TeV) ⋍ 8 × 10 −12 photons cm −2 s −1, and indicates a rather steep integral spectrum in the energy region 1–3 TeV with a power-law index α ⋍ 1.6–1.8.
