Basin stability of the two stable solutions computed from 100 samples. In red: basin stability of the periodic solution. In blue: basin stability of the equilibrium. Error bars correspond to the standard error of the size estimation of the Monte-Carlo method due to sub-sampling equation (7). In black: basin stability computed with the analytic expression of the basin boundary (circle of known diameter X_2π− given in (3)). The region of multistability is shaded in grey.
