Maps of synchrotron radio (left), X-ray (center), and IC γ-ray (right) surface brightness synthesized from run Grad-BZ-g1, assuming quasi-perpendicular (top), and quasi-parallel (bottom) injection models. The adiabatic index is γ = 5/3. The maps have been synthesized adopting model B of E_max shown in Fig. 8. The relevant angles are φ_B = 45° and φ_∇B = 45°. The angle between  ⟨ B ⟩  and ∇| ⟨ B ⟩ | is 90°.
