Appendix 8—figure 1. Rescaling of the size of the active region with active tension difference.

(a) Plot of $l_a^{\prime }/L$ as given by Equations 213; 214. This illustrates the rescaling of the active region size as a function of the tension difference $\delta \zeta$, for initial values $l_a/L_0=0.1,0.3,0.5,0.7,0.9$ (blue to purple). (b) Shapes corresponding to two points on the $l_a/L_0=0.5$ curve.
