N2 - We present the final results from a high sampling rate, multi-month, spectrophotometric reverberation mapping campaign undertaken to obtain either new or improved Hβ reverberation lag measurements for several relatively low-luminosity active galactic nuclei (AGNs). We have reliably measured the time delay between variations in the continuum and Hβ emission line in six local Seyfert 1 galaxies. These measurements are used to calculate the mass of the supermassive black hole at the center of each of theseAGNs.We place our results in context to the most current calibration of the broad-line region (BLR) RBLR-L relationship, where our results remove outliers and reduce the scatter at the low-luminosity end of this relationship.We also present velocity-resolvedHβ time-delay measurements for our complete sample, though the clearest velocity-resolved kinematic signatures have already been published.
