Notes. Best-fitting parameters of the virial relations (see Eq. (2)) between the MBH = f × Mvir, with ⟨ f ⟩ = 4.31 (Grier et al. 2013), and the average VP given by the mean FWHM (once the Hβ was converted into Hα) and the mean L2−10 keV (using Eq. (4) to convert L14−195 keV). Columns are (1) sample bulge type; (2) and (3) zero point and slope of the virial relation; (4) number of objects of each sample; (5) and (6) Pearson correlation coefficient with its t-student probability; (7) logarithmic spread of the data on the MBH axis; and (8) intrinsic logarithmic spread of the data on the y-axis as before.
In this sample different virial factors for classical and/or elliptical and pseudo-bulges were used as follows: fCB = 6.3, fPB = 3.2 (Ho & Kim 2014).
