Appendix 1—figure 3. Solutions to Equation 52 for $g=1$, $w=-1.8$, $\gamma =0.2$.

We can then find the shape of the bump $u(x)$ for given values of $g$, +$w$ and γ, from which we can obtain the profile $v(x)=g𝒩(u(x))$ that we need for the calculation of the storage capacity. Some examples of the obtained profiles, for different values of γ, are shown in Appendix 1—figure 4.
