Figure 1: Steady state analytic relations between the velocities of neutrals and charges are compared to an overlaid steady C-shock (diamonds). The parameters of the shock are u=20 km s^{-1}, n=10^{4} cm^{-3} and b=0.1, time is t=10^{5} yr. The velocities in the shock frame are computed using a velocity of the shock front of 0.13 km s^{-1}, inferred from Fig. 3d of Paper I. | |

Figure 2: Steady state analytic relations between pressure and mass density are compared to an overlaid future C-shock (diamonds). The parameters of the shock are u=20 km s^{-1}, n=10^{4} cm^{-3} and b=0.1, time is t=10^{2} yr. The additional necessary parameters and are read in the shock model at the end of the precursor (they are not fitted). | |

Figure 3: We plot the values and steady velocities for each variables of S in each zone of snapshot t=200 years for the shock with parameters b=0, n=10^{4} cm^{-3}, and u=20 km s^{-1}. Each dot represents the steady velocity of one variable computed thanks to expressions (44) and (45). The error bars are evaluated zone per zone on these values. We indicate the computational domains associated to the adiabatic front and the relaxation layer of the shock. | |

Figure 4: Trajectory and velocity away from the piston of the J-shock with parameters b=0, n=10^{4} cm^{-3}, and u=20 km s^{-1} (from Paper I). Overlaid diamonds are the steady velocities v averaged over all variables and all zones, for each snapshot analysed. | |

Figure 5: Same as Fig. 3, but for a partly ionising shock of parameters b=0, n=10^{4} cm^{-3}, and u=40 km s^{-1} at time t=220 years. Here, the scale of the plot is linear, so that the dispersion is in fact much greater than for the non-dissociative shocks, even in the second plateau. | |

Figure 6: Same as Fig. 3, but for time t=100 years of the future C-shock with b=0.1, n=10^{4} cm^{-3}, and u=20 km s^{-1}. We also show the steady velocity for the magnetic field. | |

Figure 7: Same as Fig. 4, but for a C-shock of parameters b=0.1, n=10^{4} cm^{-3} and u=20 km s^{-1}. Curves plot the trajectory and velocity of the neutral (solid) and charged (dashed) viscous fronts. Diamonds are the quasi-steady velocities of the relaxation layer and adiabatic front. Triangles are the quasi-steady velocities of the magnetic precursor. | |
