Radial distribution of line emission as used in Eq. (6) for f (red line), f₂ (blue line) and the sum of the two components at φ  =  0.5 π (where we put the additional clouds in azimuthal direction). r_rm is the center of the overall BLR and the additional clouds are shifted inwards according to the ratio of v_rot and v_rot, 2 squared. Together with the distribution in azimuthal direction (compare Fig. 10) the additional clouds are responsible for approximately 5% of the total BEL flux.
