Optical-UV X-ray SED on our 3 × 3 M_BH-λ_Edd grid overlaid by best-fit bootstrap models, with red for disk (DK), green for warm corona (WC), and blue for hot corona (HC). The legend gives the source number, median M_BH, λ_BH, best fitting statistic in each bin. A toy model illustrating the disk-corona size (warm corona radius R_WC, hot corona radius R_HC, both in units of R_g) is shown on the top right of each panel. We note the potential star-formation contamination in two upper-left bins with low λ_Edd – high M_BH when interpreting the results.
