BLR structures in NGC 7469, NGC 3783, NGC 5548 (two epochs), and 3C 390.3 scaled to their individual continuum luminosities at 5100 Å (based on corrected turbulent velocities vturb). Same as Fig. 17, but the emitting regions of the different lines are drawn in different colors: C ivλ1549 (blue), Si iv+O iv]λ1400 (black), He iiλ1640 (cyan), He iiλ4686 (green), Hβ (red). The individual line-emitting regions of the two narrow line Seyfert galaxies NGC 7469 and NGC 3783 are connected by a dashed line to aid the eye. The line-emitting regions of NGC 5548 are connected by a solid line.
