Probability distributions of bump widths for a non-Gaussian threshold distribution. Logarithm of the probability of the bump width Δ when the local probability distribution is given by a shifted exponential and the covariance function is Gaussian: all bumps (top), stable bumps (middle), unstable bumps (bottom). Parameter values are \(\sigma=1\), \(\mu =-1\), \(\lambda=1\), \(N=32\), \(\kappa=1\), \(L=2 \pi\) and \(h_{0}=0.05\)
