BLR radius – quasar luminosity relations shown as a function of the luminosity at 5100 Å (continuous lines) for the C IV (Kaspi et al. 2021, in blue), Mg II (Yu et al. 2023, in green), and Hβ (Bentz et al. 2013, in red) BLRs. The microlensing Einstein radii of lensed quasars from the compilation of Mosquera & Kochanek (2011) are superimposed (black diamonds).
