Results for our reference case B (M = 4, η = 10^-2, ℒ_kin ~ 1.1 × 10⁴² erg s^-1), at t = 640 time units, 4.9 × 10⁷ yr). The spatial units are in jet radii (100 pc) and the image extends over 12 kpc in the jet direction and over 6 kpc in the transverse direction. Cuts in the (y,z) plane of (top) the logarithmic density distribution in units of jet density, (center) tracer distribution, and (bottom) distribution of the longitudinal velocity of the external medium in units of c_sj.
