Models of γ-ray emission based on hadronic (red) and leptonic (blue) one-zone scenarios, for HESS J1702-420A – left panel – and HESS J1702-420B – right panel. The best-fit spectra, under the assumption of simple power law distribution of the underlying particle populations, are shown as solid lines, while the shaded areas and dotted lines represent the 1σ statistical error envelope and extrapolations outside the fit range, respectively. The H.E.S.S. and Fermi-LAT flux points are also shown, for reference purpose. Fit results were obtained with a 3D fit of H.E.S.S. data.
