Notes. Number of excess ( $N_{\rm excess}$) and background ( $N_{\rm backgr.}$) events, resulting significances S, lower cuts in event energy, integral fluxes F above $E_{\rm min}=250~{\rm GeV}$ for the April 2006 data and $E_{\rm min}=450~{\rm GeV}$ for the June 14, 2006 data (in units of $10^{-10}~{\rm cm}^{-2} ~{\rm s}^{-1}$), fit quality of a constant-flux fit to the individual observation nights (see Fig. 2), and power-law fit results for the differential energy spectra of ${\rm d}F/{\rm d}E=f_0 \cdot (E/E_0)^{-\alpha}$ with $E_0=0.5~{\rm TeV}$ for the April 2006 data and $E_0=1.0~{\rm TeV}$ for the June 14, 2006 data, respectively; f0 in units of $10^{-10}~{\rm TeV}^{-1}~{\rm cm}^{-2}~ {\rm s}^{-1}$.
