Top to bottom: comoving densities, Lorentz factors of the fluid and shock fronts, pressure, and shock strengths. The hydrodynamical quantities are measured downstream of shocks (‘d,3’ downstream of the RS, ‘d,2’ for the FS), at the CD by averaging over a few cells crossing the interface, or on each side of it (CD₃, CD₂) for the density. Legend is the same for all panels. The derived Lorentz factor of the shock fronts is displayed with the measured ones. Densities and pressures are in units of the values behind the RS in the planar case and rescaled to (r/R₀)². We smoothed the numerical oscillations in data by a rolling average. Horizontal dashed lines show the corresponding analytical values from R24a.
