Comparison between the narrow [O III] line and the broad Hα fluxes. Red squares are BLOs, black circles are HIGs, with empty symbols representing upper limits. The fluxes are in erg cm-2 s-1. The solid line marks the average ratio between the two emission lines as measured in BLOs, (FHα broad/F[O III] ~ 8). The dashed lines illustrate a change of a factor of 4 in this value.
