Notes. Bolometric corrections $k_{bol} (5100 Å)$ $k_{\mathrm{bol}}(5100\,\AA)$ and L₅₁₀₀ [erg s⁻¹] luminosity of the AD are calculated as an extension of Netzer (2019) using the Slone & Netzer (2012) model. θ is the inclination of the AD to the line of sight. The AD model adopts a spin parameter = 0.7, and an accretion rate of 2.6 ⋅ 10⁻³ M_⊙/year, corresponding to L_bol = 1.56 ⋅ 10⁴³ erg/s. The BLR radii uncertainties correspond to the 68% confidence interval and are calculated using Monte Carlo sampling, incorporating the inner scatter and coefficients’ uncertainties for the R_{BLR, Hβ}(L₅₁₀₀) relation (Bentz et al. 2013).
