| contents | We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2m telescope at the Calar Alto Observatory. This follows a similar earlier study of another sample of 15 objects reported by Hu et al. (2021). Among the 11 PG quasars, 8 objects have the H$β$ time lags measured for the first time, while the other 3 objects were observed in previous campaigns, but only had highly uncertain H$β$-lag measurements. Long-term light curves are presented of photometric $V$-band, spectroscopic 5100 Å continuum, and the H$β$ emission line, lasting for $\sim$3--6 years with a cadence of $\sim$6--14 days. Accurate H$β$ time lags ranging from $\sim$20 to 150 days in the rest frame are obtained. The estimated virial masses of the central supermassive black holes range from $\sim$(3--300)$\times10^7 M_\odot$. Combining these results with those reported in Hu et al. (2021), we now have 26 PG quasars, with representative properties, having reliable H$β$ time-lag measurements from our long-duration high-cadence campaign. A tentative fit to the relation between the H$β$ time lag and the continuum luminosity for these 26 objects gives a slope of 0.53. |
