Jet classes in the ℳ_ms, j − 1/ε_j plane for different magnetic field configurations and magnetic pitch angles according to the dominant energy type for a given jet flow velocity, v_j = 0.95c. The lines of constant magnetization are drawn. Kinetically dominated jets, magnetically dominated jets, and hot jets are placed in the diagram with the help of three (red) lines corresponding to models with c² = ε_j, β_j = 1, and β_jε_j = c². Pure hydrodynamic models are placed on the β_j = 0 line, which bounds a forbidden region (in violet) corresponding to unphysical models with negative magnetic energies. The distribution on the ℳ_ms, j − 1/ε_j diagram of the models we considered is superimposed.
