Measurements and fits of the BH mass-stellar mass relation. The data points with errors are from JWST measurements (red; see the appendix) and other high-z measurements (yellow) from I21. The local AGN measurements (green) and the local IG measurements (blue), both from RV15, are shown without errors, but the errors are taken into account in the analysis. The dashed lines show the best fits to each of the datasets separately, and the solid black line shows the best fit combining the high-z data and the local IG data. The grey band shows the scatter in the latter fit.
