cds-question@unistra.fractive-galactic-nucleiquasarsspectroscopyWe present results of long-term (1987-2010) optical spectral monitoring of the broad-line radio galaxy Arp 102B, a prototype of an active galactic nucleus with double-peaked broad emission lines that are commonly assumed to be emitted from an accretion disk. To explore the structure of the broad-line region (BLR), we analyze the light-curves of the broad H{alpha} and H{beta} lines and the continuum flux. We aim to estimate the dimensions of the broad-line emitting regions and the mass of the central black hole. We used the cross correlation function to find lags between the lines and continuum variations. We investigated the correlation between line and continuum fluxes in more detail, and explored periodical variations of the red-to-blue line flux ratio using Lomb-Scargle periodograms.2013A&A...559A..10Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A10CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/559/A10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A10https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap3.203943175748454e-19 3.8949892233750168e-19OpticaldefaultJ/A+A/559/A10/observationsObservations of the continuum and line fluxes for the 142 nightsrecnoRecord number assigned by the VizieR team.
