Caption: Figure 4.
Flux amplitude and FWHM posteriors from our stacked Hα fits. Stacks with detected broad Hα emission have their best-fit flux and FWHM measurements indicated by pink stars. Full BH mass posteriors are obtained by computing masses with the full flux and FWHM posteriors. BH mass contours of 105 and 106 M⊙ are shown with dashed black lines. The BH mass prescription we use is discussed in Section 5.1.
