Entropy distribution in models T10-l1-r1 (left column) and T10-l2-r1 (right column) for different times after bounce as indicated in every panel. The figures are plotted such that the polar axis is oriented horizontally with “south” (θ = π) on the left and “north” (θ = 0) on the right. The thin grey line marks the shock radius. In the panel for t = 1500 ms of model T10-l1-r1, the radial lines mark the angular directions at θ = 25 degrees (green line) and 100 degrees (red line), along which radial profiles are shown in Fig. 6.
