Simple proxies for L_bol for Seyfert galaxies. Left: L_[O III] corrected for extinction; right: L_[O III] without extinction correction. The thick black line represents our regressions as given by Eq. (1) (left panel) and Eq. (2) (right panel) considering all 77 071 Seyferts with L_bol and L_[O III] values (some which are not drawn on the panels above due to the [O II] selection cut). In the left panel the red line represents the relation of Kauffmann & Heckman (2009), while in the right panel it represents the relation from Heckman et al. (2004). The blue line in the right panel represents the relation of Spinoglio et al. (2024) for Seyfert 2 galaxies.
