英文摘要We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2 m telescope at the Calar Alto Observatory. This follows a similar earlier study of another sample of 15 objects reported by C. Hu et al. (2021). Among the 11 PG quasars, eight objects have the H beta time lags measured for the first time, while the other three objects were observed in previous campaigns but only had highly uncertain H beta-lag measurements. Long-term light curves are presented of photometric V-band, spectroscopic 5100 & Aring; continuum, and the H beta emission line, lasting for similar to 3-6 yr with a cadence of similar to 6-14 days. Accurate H beta time lags ranging from similar to 20 to 150 days in the rest frame are obtained. The estimated virial masses of the central supermassive black holes range from similar to(3-300) x 107M circle dot. Combining these results with those reported in C. Hu et al. (2021), we now have 26 PG quasars, with representative properties, having reliable H beta time-lag measurements from our long-duration high-cadence campaign. A tentative fit to the relation between the H beta time lag and the continuum luminosity for these 26 objects gives a slope of 0.53.
