Bumps for a Gaussian threshold distribution. Stable (solid) and unstable (dashed) solutions corresponding to the two points in Fig. 9 with $x_1$ slightly less than 2. The threshold is shown dash-dotted. Parameter values are $\kappa =1$, $ϵ=0.01$, $\sigma =1$, $\alpha =5$, $B=0.76$, $\beta =3$ and $h_0=0.05$
