Fig. 4.

Ratio of the BLR to continuum sizes as a function of the quasar bolometric luminosity. The RM Hβ to 5100 Å time lag ratios from Netzer (2022) are in black (squares). Our microlensing half-light radius ratios are shown in red (diamonds). The continuous line represents the average of our sample.
