Caption: Figure 17.
Distribution of the jet radius R in NGC 6251 as a function of the jet axial distance z (deprojected with M = 6 × 108 M⊙ and θv = 19°) from the SMBH in units of rg (T16). This is similar to Figure 15; the vertical/horizontal scales and other components, which are shown in this figure, are identical.
