Similar to Fig. 8 but for the cloud distribution of the best-fit BLR model of ID#5 (Q 0226–1024). The BLR clouds have almost equal sizes, pertaining to the lack of preference of the BLR emission to originate from either side. However, the moderate opacity on the midplane affects the blueshifted clouds more than the redshifted clouds, as indicated by the slightly lower number of blueshifted clouds compared to the redshifted clouds. This causes the redshifted wing of the Hα emission line to be slightly higher than the blueshifted wing.
