Comparison of various AGN luminosity indicators are shown for the unobscured QSO samples of Husemann et al. (2013b, 2014), and Liu et al. (2014), and for the obscured QSO sample of Liu et al. (2013a) in the upper panels. Here we consider the continuum luminosity at 8 μm (L_{8 μm}), total [O iii] luminosity (L_{[O iii]}), broad Hβ luminosity (L_{broad Hβ}) and continuum luminosity at 5100 Å (L₅₁₀₀) as independent AGN luminosity indicators. The corresponding distributions in the luminosity ratios are shown in the lower panels. For obscured QSOs only L_{[O iii]} and L_{8 μm} can be measured because the broad lines from the BLR and the continuum from the accretion disc are obscured and unobservable.
