Abstract Using different kinds of velocity tracers derived from the broad Hβ profile (in the mean or rms spectrum) and the corresponding virial factors f, the central supermassive black hole masses ( ) are calculated for a compiled sample of 120 reverberation-mapped (RM) active galactic nuclei (AGNs). For its subsample of RM AGNs with measured stellar velocity dispersion ( ), the multivariate linear regression technique is used to calibrate the mean value f, as well as the variable FWHM-based f. It is found that, whether excluding the pseudobulges or not, the from the Hβ line dispersion in the mean spectrum ( ) has the smallest offset rms with respect to the relation. For the total sample excluding SDSS-RM AGNs, with respect to from or that from the Hβ line dispersion in the rms spectrum ( ), it is found that we can obtain from the with the smallest offset rms of 0.38 or 0.23 dex, respectively. It implies that, with respect to the Hβ FWHM, we prefer to calculate from the single-epoch spectrum. Using the FWHM-based f, we can improve the calculation from FWHM(Hβ) and the mean f, with a decreased offset rms from 0.52 to 0.39 dex with respect to from for the subsample of 36 AGNs with . The value of 0.39 dex is almost the same as that from and the mean f.
