cds-question@unistra.frquasarsactive-galactic-nucleivisible-astronomyspectroscopyphotometryextinctionredshiftedblack-holesWe 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+ (2021, J/ApJS/253/20). 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{AA} continuum, and the H{beta} emission line, lasting for ~3-6yr with a cadence of ~6-14d. Accurate H{beta} time lags ranging from ~20 to 150 days in the rest frame are obtained. The estimated virial masses of the central supermassive black holes range from ~(3-300)x10^7^M_{sun}_. Combining these results with those reported in Hu+ (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 0.53.2025ApJS..278...61Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/278/61CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/358/77 : Hamburg/ESO survey for bright QSOs.
