Broadband SED for the sub-region of HESS J1731−347 that is observed in X-rays (see Fig. 5, right, for region definition). A purely leptonic (top) and a hadronic (bottom) scenario are shown and the corresponding parameters for both models are presented in Table 2. The infrared (IR) seed photons energy density and temperature were respectively set to 1 eV cm^-3 and 40 K following the model from Porter et al. (2008) for a galactocentric radius of 4 kpc. The flux from the nearby Fermi source 1FGL J1729.1−3452c is represented and used as an upper limit.
