cds-question@unistra.frseyfert-galaxiesspectroscopyA large reverberation-mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for H{beta} {lambda}4861 and He II {lambda}4686 and a central black hole mass measurement M_BH_{approx} 1x10^7^ M_{sun}_, consistent with previous measurements. A very low level of variability during the monitoring campaign precluded meeting our original goal of recovering velocity-delay maps from the data, but with the new H{beta} measurement, NGC 7469 is no longer an outlier in the relationship between the size of the H{beta}-emitting broad-line region and the luminosity of the active galactic nucleus. It was necessary to detrend the continuum and H{beta} and He II {lambda}4686 line light curves and those from archival UV data for different time-series analysis methods to yield consistent results.2014ApJ...795..149Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/795/149CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AZh/71/200 : Spectral Investigation of NGC 7469 (Doroshenko+, 1994)J/PAZh/21/652 : Optical variability in NGC 7469 (Lyuty+, 1995)J/ApJ/755/60 : Reverberation mapping for five Seyfert 1 galaxieshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/795/149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/795/149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/795/149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/795/149https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/795/149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/795/149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/795/149/table1Continuum FluxesrecnoRecord number assigned by the VizieR team.
