VizieR Online Data Catalog: 13yr of spectrophotometrically monitored QSOs (Kaspi+, 2021)

The sample, observations, and data processing are described in detail in Paper I (Kaspi+ 2007ApJ...659..997K). In this paper we report the final results from this campaign after 18yr of photometric and 13yr of spectroscopic monitoring.

The photometric sample consists of 11 high-luminosity quasars with observed magnitude of V<~18 and redshift in the range 2<~z<~3.4. Six of the objects in our sample are radio loud and five are radio quiet. Photometric observations were obtained at the Wise observatory 1m telescope in the Johnson-Cousins B and R bands from 1995 to mid-2013.

Spectroscopic observations were performed for 6 of the 11 photometrically monitored AGNs at the Hobby-Eberly Telescope (HET). Spectra were obtained starting in 1999 with the Low Resolution Spectrograph (LRS), which began its primary observations in 1998, and spectroscopic observations continued until the instrument was decommissioned in mid-2013. The total program time amounted to roughly 12hr of HET time each year.
