 (a0) and (b0), $\alpha = 0.0$; (a0) and (b0), $\alpha = 0.0$; (a0) and (b0), $\alpha = 0.0$. The mobility parameters are set at $\gamma_{S} = \gamma_{A} = - 0.0$ (the black squares); $\gamma_{S} = \gamma_{A} = 0$ (the blue circles), and $\gamma_{S} = \gamma_{A} = 0.0$ (the red triangles). The other parameters are the same as in [Fig. 0](#f0000){ref-type="fig"}.
