A large reverberation-mapping study of the Seyfert 1 galaxy NGC7469 has yielded emission-line lags for H beta lambda 4861 and He He II lambda 4686 and a central black hole mass measurement M-BH approximate to 1 x 10(7)M(circle dot) , consistent with previous measurements. A very low level of variability during the monitoring campaign precluded meeting our original goal of recovering velocity-delay maps from the data, but with the new H beta measurement, NGC7469 is no longer an outlier in the relationship between the size of the H beta-emitting broad-line region and the luminosity of the active galactic nucleus. It was necessary to detrend the continuum and H beta and He He II lambda 4686 line light curves and those from archival UV data for different time-series analysis methods to yield consistent results.
