Fig 6. Illustration of finite size effects in the shock phase, based on the density profile for $\tilde{\Gamma }=0.05$, $\tilde{\alpha }=0.2$, $\tilde{\beta }=0.16$ and L = 1.

The blue dots represent the numerical results for N = 500 sites,whereas red dots are for N = 1000 sites. The solid black line corresponds to the analytical solution.
