Notes.
The MBH values are virial estimates based on Hβ in HS 0810+2554 (Assef et al. 2011), and on C IV in SDSS J1353+1138 (Chartas et al. 2021), respectively. The C IV-based measurement of MBH in SDSS J1353+1138 has been corrected following the prescription for C IV-based virial black hole mass estimates published in Coatman et al. (2017).
The values of LBol are corrected for the lens magnification and computed as average of the two independent estimates of the AGN bolometric luminosity, obtained through the 2–10 keV bolometric correction (Lusso et al. 2012) and from the continuum luminosity at 1450 Å (Assef et al. 2011; Runnoe et al. 2012).
