cds-question@unistra.fractive-galactic-nucleivisible-astronomybroad-band-photometryThe Lick AGN Monitoring Project targeted 13 nearby Seyfert 1 galaxies with the intent of measuring the masses of their central black holes using reverberation mapping. The sample includes 12 galaxies selected to have black holes with masses roughly in the range 10^6^-10^7^M_{sun}_, as well as the well-studied active galactic nucleus (AGN) NGC 5548. In conjunction with a spectroscopic monitoring campaign, we obtained broadband B and V images on most nights from 2008 February through 2008 May. The imaging observations were carried out by four telescopes: the 0.76m Katzman Automatic Imaging Telescope, the 2m Multicolor Active Galactic Nuclei Monitoring telescope, the Palomar 60 inch (1.5m) telescope, and the 0.80m Tenagra II telescope. Having well-sampled light curves over the course of a few months is useful for obtaining the broad-line reverberation lag and black hole mass, and also allows us to examine the characteristics of the continuum variability. In this paper, we discuss the observational methods and the photometric measurements, and present the AGN continuum light curves. We measure various variability characteristics of each of the light curves. We do not detect any evidence for a time lag between the B- and V-band variations, and we do not find significant color variations for the AGNs in our sample.2009ApJS..185..156Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/185/156CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/314/43 : NGC 5548 Profile variability (Kollatschny+ 1996)J/A+A/320/405 : NGC 5548 continuum light curve (Sergeev+ 1997)J/AJ/116/102 : NGC 5548 BR photometry (Tyson+ 1998)J/A+A/371/79 : NGC 5548 UBVRI phot. and Halpha, Hbeta fluxes (Dietrich+, 2001)J/A+A/422/925 : Profile variability in lines of NGC 5548 (Shapovalova+ 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/185/156https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/185/156http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/185/156https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/185/156https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/185/156http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/185/156GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/185/156/table1 (Properties of AGNs in the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/185/156/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/185/156/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/185/156/table1?GETtext/xml+votable180.050000true156.38041751.6763890.0055555555555555566/5989 6028 6087 8922 11191 11388 25054 25585 26181 28517 29795 31676 43806https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/185/156?format=asciiOpticaldefaultJ/ApJS/185/156/table1Properties of AGNs in the samplerecnoRecord number assigned by the VizieR team.
