The temperatures (red lines with the scale on the right ordinate) and densities (black lines with the scale on the left ordinate) after the shock are shown for n_H = 2 × 10⁴cm^-3 (left panel) and n_H = 2 × 10⁵cm^-3 (right panel) with varying shock velocities of v_s = 10, 20, 30, and 40 km s^-1. Different velocities are indicated with solid lines (10 km s^-1), dotted lines (20 km s^-1), dashed lines (30 km s^-1), and dash-dotted lines (40 km s^-1).
