Optical extinction of the accretion disk derived from the SED fit (E(B − V)_AGN, SED) versus the one derived from the Balmer decrement of the Hα and Hβ broad emission lines (E(B − V)_AGN, BD). The grey area represents the 1:1 relation and its 1σ uncertainty from Dong et al. (2008). A random contribution of ±0.003 was added to E(B − V)_SED to avoid the superposition of points with the same value. The inset shows a zoom of those objects with E(B − V)_SED < 0.1. Symbol and colour coded as in Fig. 1, except for AGN with E(B − V) compatible with no obscuration, that are represented with empty triangles pointing down.
