Notes. Note that the derivation of uncertainties for black hole masses is complex since it includes measurement uncertainties (e.g. of the flux measurement) but also the intrinsic scatter of the relations. Usually, the uncertainty will be at least 0.5 dex.
Correction for the difference between NIR (σCO) and optical (σopt) stellar velocity dispersion according to Riffel et al. (2015).
Note that the MBH − Lbulge relation is not a good estimator for active galaxies according to Busch et al. (2014).
