Bump solutions as a function of ϵ for a Gaussian threshold distribution. Top: average number of total solutions (blue) and stable solutions (green) of (32)–(33) for a Gaussian threshold distribution. Bottom: fraction of solutions which are stable. Parameter values are $\alpha =5$, $B=0.76$, $\beta =3$, $h_0=0.05$, $\kappa =0.5$ and ${\sigma }^2=4$
