Azimuthal profiles of the synchrotron radio (red), X-ray (blue), and IC γ-ray (green) surface brightness synthesized from runs Grad-BZ-g1 (left; the relevant angles are φ_B = 90° and φ_∇B = 0°) and Grad-BX-g1 (right; φ_B = 90° and φ_∇B = 90°), assuming quasi-perpendicular (top), isotropic (middle), and quasi-parallel (bottom) injection models. The adiabatic index is γ = 5/3. The azimuth is measured counterclockwise from the north (see Figs. 4 and 5). The corresponding azimuthal profiles of E_max used to derive the curves of this figure are in Fig. 3.
