At shock velocities \\beta_s\\equiv v_s/c\\gtrsim 0.1, the shock transition region is far from thermal equilibrium, since the transition crossing time is too short for the production of a black-body photon density (by Bremsstrahlung emission). In this region, electrons and photons (and positrons) are in Compton (pair) equilibrium at temperatures T_s significantly exceeding the far downstream temperature, T_s\\gg T_d\\approx 2(\\varepsilon n_u \\hbar^3c^3)^{1/4}.
