    \caption{Fit results for distinct regions of the SNR. Given are
      for each region the photon index resulting from a~power-law fit,
      the best-fit~$\chi^2$ and the number of degrees of freedom~(d.o.f.), the integral flux above 1~TeV and the significance of the excess events in units of standard deviation~$(\sigma)$. The
      background for each region was determined from the same field of
      view, as described in Sect.~\ref{subsec:SpectralAnalysis}, for
      each region separately, and hence the background estimates for
      different regions are not independent. The first~row is the fit
      result of the whole SNR for comparison. For the whole table, the
      upper fit range was restricted to 8~TeV to avoid biases due to
      the deviation from a~power law at high energies.}
