Heights in time of the “shock” seen in v_∥ (blue curve; the shock is actually smoothed for a while after meeting the equipartition level) and the shock in v_⊥ (dashed orange curve) as well as the position of the a = c equipartition level (red), for the case of the 30° inclined magnetic field. Clearly, the equipartition level is advected with the slow shock for several seconds.
