One-dimensional y-averaged profile for density (top), x-directional three-velocity (second from the top), z-directional four-velocity (third from the top), momentum tensor (bottom, red line), and Maxwell stress tensor (bottom, blue line) at tω_pe = 600. The regions 1, 2, and 3 indicate the low-density region, the shock downstream, and the shock upstream, respectively. CD and SF represent the contact discontinuity and the shock front, respectively.
