Black hole mass function for broad-line AGNs derived from our sample. The blue region contains 68% of the probability for the BHMF, and the solid line running through it denotes the best-fit BHMF, defined to be the posterior median. The orange shaded region contains 68% of the probability on the BHMF for Type 1 quasars above the SDSS flux limits, and the dashed line denotes the posterior median. The vertical solid line denotes the mass below which the completeness in the BHMF drops to ≲ 10% for the flux-limited SDSS sample, and thus mass bins below this marker are highly incomplete and the extrapolation becomes highly uncertain. We do not find any evidence for a turnover in the Type 1 quasar BHMF above the 10% completeness limit in M _BH.
