cds-question@unistra.fractive-galactic-nucleiinfrared-photometryvisible-astronomybroad-band-photometryWe determine interband lags between variations in the B band and variations in the V, R, and I bands for 14 active galactic nuclei observed at the Crimean Astrophysical Observatory. The computed lags range from tenths of a day to several days, and it is positive (that is, V, R, and I bands lag behind the B band) in most cases, except for a few cases for the V filter.2005ApJ...622..129Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/622/129CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/19 : X-ray lightcurves of bright AGNs from Ginga (Hayashida+ 1998)J/PAZh/21/652 : Optical variability in NGC 7469 (Lyuty+, 1995)J/A+A/314/43 : NGC 5548 Profile variability (Kollatschny+ 1996)J/A+A/320/405 : NGC 5548 continuum light curve (Sergeev+ 1997)J/PAZh/23/409 : Spectrophotometry of Mrk 509 (Chuvaev+, 1997)J/ApJS/115/185 : 3C 390.3 BVRI and H photometry (Dietrich+, 1998)J/PAZh/25/403 : Optical variability of NGC 4151 (Lyuty+, 1999)J/A+A/376/775 : UBVRI and H-beta observations of 3C 390.3 (Shapovalova+ 2001)J/A+A/371/79 : NGC 5548 UBVRI phot. and Halpha, Hbeta fluxes (Dietrich+,J/A+A/422/925 : Profile variability in lines of NGC 5548 (Shapovalova+ 2004)J/A+A/437/87 : Mrk 335 photometry in 1995-2004 (Doroshenko+, 2005)J/A+A/486/99 : Long-term spectral variability of NGC 4151 (Shapovalova+,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/622/129https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/622/129http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/622/129https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/622/129https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/622/129http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/622/129GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/622/129/table3 (Nuclei variability characteristics for the B filter)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/622/129/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/622/129/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/622/129/table3?GETtext/xml+votable180.050000true119.500212539.34141310.0055555555555555566/1405 4439 6535 6977 7642 7921 8922 10912 10927 16301 19283 19883 22890 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/622/129?format=asciiOpticalInfrareddefaultJ/ApJ/622/129/table3Nuclei variability characteristics for the B filterzRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
