Parameter space plots for the variation of the slopes, ϵ_i as function of b and s while keeping the d parameter fixed. The columns show from left to right, the slope of the Compton stage, ϵ_C, the slope of the synchrotron stage, ϵ_S, and the slope of the adiabatic stage, ϵ_A. The exponent for the evolution of the Doppler factor, d, is from top to bottom d = −0.45, d = −0.30, d = −0.15, and d = 0. The black dashed line corresponds to a constant u_B/u_e ratio with distance (b_eq = (s + 2)/3)), i.e. to the left of this line the jet flow tends to be magnetically dominated with distance and to the right the jet tends to be particle energy dominated with distance.
