AGN luminosity (L5100 Å for blue symbols and L2 kev for red symbols) vs. the luminosity of the broad Hα. The grey line represents the relation of Greene & Ho (2005) with the dotted lines corresponding to the 0.2 dex scatter, while the black line is for the Stern & Laor (2012) relation with a scatter of 0.35 dex. The sources for which the BEL would have been securely detected if present are labelled by squares. While this is the case for 91% (blue squares) of the sample based on L5100 Å, from L2 kev it is only 21% (red squares). Sources that may have their BEL diluted by the host galaxy are labelled by open green triangles.
