Notes. Table summarizing the different M_BH estimations found in the literature and the one we made with ML. The M_BH is in M_⊙, and only the log of values are indicated. When multiple M_BH estimations using the same method were available, we report here their mean, the highest values in superscript, and the lowest in the subscript. (1) Galaxies ID ; (2) Mean of the M_BH probability distribution obtained with ML and the PVD as input (the errors are at 1σ); (3) Same as the previous column but with the moment maps as input; (3) Mean of the M_BH estimations with the M – σ (intrinsic errors of 0.3 dex) ; (4) M_BH calculated with reverberation mapping (intrinsic errors of 0.4 dex); (5) FPBH masses (intrinsic errors of 0.4 dex); (6) M_BH estimations references 1: Peterson et al. (2004), 2: Bian & Gu (2007), 3: Wang et al. (2007), 4: Beckmann et al. (2009), 5: van den Bosch (2016), 6: She et al. (2017), 7: M-σ estimation made with the Hyperleda data, 8: FPBH mass estimated from the XMM-Newton and the FIRST data, 9: FPBH mass estimated from the XMM-Newton and the NVSS data).
