Azimuthal intensity ratio R_max (i.e. the ratio of the maxima of intensity of the two lobes around the shell) and azimuthal distance θ_D (i.e. the distance in degrees of the two maxima of intensity around the shell) versus the angle between ∇B and the vertical line passing through the remnant center φ_∇B, for an aspect angle φ_B = 90°, and for the three models of E_max shown in Fig. 8. The run is Grad-BZ-g1. For isotropic injection, curves for R_max in γ-rays and curves for θ_D in radio and X-rays are not shown, the values being R_max = 1 and θ_D = 180°, respectively at all φ_∇B.
