$g_{rc}$ versus $c=c_{\text{out}}/c_{\text{int}}$ with small wound $R_0/d=5$ (left) and large wound $R_0/d=50$ (right). For $R_0/d=5$, there is a transition of dominant modes under the change of $c$ while for $R_0/d=50$, there is no such a transition. In both cases, the critical $g_{rc}$ increases as $c$ increases. The effect from $c$ saturates as $c$ goes beyond $c\sim 2$
