Radiative shocks with non-equilibrium diffusion. Left column: results for the ℳ = 2 case, while the right column gives the ℳ = 5 setup. In all panels the numerical results are marked by symbols (circles and squares), the analytical solutions are represented by solid lines, and the mesh AMR level by dotted black lines. Panels a) and c): gas density as a function of distance. Panels b) and d): gas (black) and total radiative (magenta) temperatures. They also present the radiative temperatures inside the individual groups θ_g = (E_g/a_R)^{1 / 4} with more colours (see legend in panel d)).
