Notes. The regions are defined in Table A.1 and illustrated in Figs. 1 and 4 for the whole SNR and the rest of the regions, respectively. The parameter set of each region was derived for the corresponding spectral analysis listed in Table 1. All parameter sets were derived for spectra in the energy range from 0.3 TeV to 30 TeV and assuming a reference energy for the fit E0 of 1 TeV; F(> 1 TeV) and F(0.3− 30 TeV) represent the integral fluxes above 1 TeV and in the fitted range from 0.3 TeV to 30 TeV, respectively.The last column lists the equivalent significance in Gaussian standard deviations σ of the preference of a power law with exponential cutoff model with respect to a simple power law model, according to the likelihood ratio test. The quoted errors represent 1σ statistical (systematic in parentheses) uncertainties.
