Evolution of different quantities along the cut plotted in Fig. 5 for the same instants reproduced in that image. The x and z coordinates along that line are given as abscissas in the bottom and top axes, respectively. Left panels: evolution of the temperature T (black lines, left axis) and ionization fraction ρ_i/ρ (blue lines, right axis) for the NEQ case (long dashed lines) and NEQ+AD (solid ones). Right panels: zoom of the gray region of the left panels. The curves are for the temperature (black), and the characteristic times τ_comp (blue) and τ_qamb (orange), keeping the long dashed lines for the purely NEQ case and solid lines for the NEQ + AD one. The tick-marks for the temperature are given on the left axis, and those for the times on the right axis. For all panels, the threshold temperature, T = 1660 K, is shown with a horizontal dash-dotted line in red.
