cds-question@unistra.frseyfert-galaxiesnarrow-band-photometryspectroscopyVariability of the continuum, H{beta}, H{gamma} and HeII(4686{AA}) fluxes of the Seyfert I galaxy Mrk 509 is studied using spectra obtained on the 2.6-m telescope of the Crimean Astrophysical observatory from 1971-1993. All the measurements of fluxes are in the relative units normalized to the flux of [OIII](5007{AA}) taken equal to 100. The flux in the line [OIII](5007{AA}) is estimated in the interval of (5.7-7.6)*10^-13^erg/cm^2^/s=(5.7-7.6)*10^-16^W/m2. The variability amplitude in the continuum is higher than in the hydrogen lines.1997PAZh...23..409Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/23/409CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/23/409https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/23/409http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/23/409https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/23/409https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/23/409http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/23/409GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/PAZh/23/409/table1Emission line and continuum fluxesNSpectrogram numbermeta.idintrecnoRecord number assigned by the VizieR team.
