Gas density snapshots at ﹩t^{\prime} =0.52﹩ for A122R95Edd1, about ﹩{\rm{\Delta }}t^{\prime} \sim 0.34﹩ after the collision, which is comparable to ﹩t^{\prime} =0.45﹩ in A122Edd1 (third column in Figure 5). The left panel is the θ = π/2 plane, and the right panel is the mid-ϕ plane. The green solid line shows the same average for the photosphere surface as defined in Equation (9).
