DSA scenario for the multiwavelength modeling of the emission, extracted with the X-ray template, toward the Cygnus Loop. Radio data are obtained as explained in Sect. 3.3. The total contribution from Bremsstrahlung, IC, and π⁰ decay isshown by the solid black line. Our best model is obtained with a total energy W_tot of 1.2 × 10⁴⁹ erg and the electron-to-proton ratio K_ep = 0.01 at 10 GeV. Protons and electrons have an energy cutoff of 15 GeV and an energy break of 62 GeV.
