Reverberation Mapping Measurements of Black Hole Masses and Broad-Line
  Region Kinematics in Mrk 817 and NGC 7469
  We present the results from a spectroscopic monitoring campaign to obtain
reverberation-mapping measurements and investigate the broad-line region
kinematics for active galactic nuclei (AGN) of Mrk~817 and NGC~7469. This
campaign was undertaken with the Lijiang 2.4-meter telescope, the median
spectroscopic sampling is 2.0 days for Mrk~817 and 1.0 days for NGC~7469. We
detect time lags of the broad emission lines including H$\beta$, H$\gamma$,
He~{\sc ii} and He~{\sc i} for both AGNs, and including Fe~{\sc ii} for Mrk~817
with respect to the varying AGN continuum at 5100~\AA. Investigating the
relationship between line widths and time lags of the broad emission lines, we
find that the BLR dynamics of Mrk~817 and NGC~7469 are consistent with the
virial prediction. We estimate the masses of central supermassive black hole
(SMBH) and the accretion rates of both AGNs. Using the data of this campaign,
we construct the velocity-resolved lag profiles of the broad H$\gamma$,
H$\beta$, and He~{\sc i} lines for Mrk~817, which show almost the same
kinematic signatures that the time lags in the red wing are slightly larger
than the time lags in the blue wing. For NGC~7469, we only clearly construct
the velocity-resolved lag profiles of the broad H$\gamma$ and H$\beta$, which
show very similar kinematic signatures to the BLR of Mrk~817. These signatures
indicate that the BLR of Keplerian motion in both AGNs seemingly has outflowing
components during the monitoring period. We discuss the kinematics of the BLR
and the measurements including SMBH mass and accretion rates.
