cds-question@unistra.fractive-galactic-nucleiinfrared-photometryvisible-astronomyWide-band photometryccd-photometryResults are presented from CCD BVRI-observations of 145 comparison stars in the neighborhoods of 14 Seyfert galaxies, 3 quasars, and 5 BL Lac objects with right ascensions of 12 to 24 hours. The magnitudes of the observed stars ranged from V=11 to V=17. The typical photometric error for stars brighter V=14 is 0.01m. The B, V, Rc, and Ic magnitudes of most of these stars were not known previously. 14'x14' finding charts are provided. These results can be used for differential photometry of the nuclei of active galaxies in the B, V, Rc, and Ic bands.2005Ap.....48..304Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Ap/48.304CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/122/2055 : UBVRIJHK photometry of AGN field stars (Gonzalez-Perez+, 2001)J/A+AS/116/403 : VRI photometry of stars in 12 BL Lac objects (Fiorucci+, 1996)J/A+AS/130/109 : BV(RI)c photometry of ON 231 (Tosti+ 1998)J/ApJS/115/185 : 3C 390.3 BVRI and H photometry (Dietrich+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Ap/48.304https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Ap/48.304http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Ap/48.304https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Ap/48.304https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Ap/48.304http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Ap/48.304GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Ap/48.304/fields (AGN field positions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Ap/48.304/fields?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Ap/48.304/fields?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Ap/48.304/fields?GETtext/xml+votable180.050000true185.38208328.2329170.005555555555555556Cone search capability for table J/other/Ap/48.304/table2 (BVRcIc magnitudes of comparison stars in the AGN fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Ap/48.304/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Ap/48.304/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Ap/48.304/table2?GETtext/xml+votable180.050000true185.37083328.2773060.0055555555555555566/8922 9299 9305 9375 9612 9613 9707 10321 11898 12604 13411 13414 13927 15351 16301 18794 19283 26131 26148 26292 28492 29795 31663 44908 49041 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Ap/48.304?format=asciiOpticalInfrareddefaultJ/other/Ap/48.304/fieldsAGN field positionsrecnoRecord number assigned by the VizieR team.
