SEDs of gamma-ray emission measured by H.E.S.S. for the three extraction regions shown in Fig. 1. Top panel: lines show the best-fit spectral models, and the bands display the statistical uncertainties based on quadratic error propagation from the inversion of the likelihood Hessian matrix. Points show the binned SEDs with their statistical uncertainties (coloured error bars with end caps) and the sum in quadrature of statistical and systematic uncertainties (grey error bars without end caps). Bottom panel: deviation of the SED points from the best-fit function as number of statistical σ. For Pointing 0, orange corresponds to the PL fit, and blue to the ECPL fit.
