Fig. 11

Upper panel: equilibrium bulk Doppler factor δeq in the jet plane altitude Z/Rs vs. observational angle iobs (μobs = cosiobs). The color scale is shown on the right. The green dashed line represents the corresponding βeq. Bottom panel: Γeq as a function of the jet altitude. The geometry is described in Sect. 3 and the source parameters are listed in Table 1.
