cds-question@unistra.frgalaxiesspectroscopyseyfert-galaxiesWe present the first results of an 8-year spectroscopic monitoring of the Seyfert 1.5 galaxy NGC 4151 carried out with a CCD spectrograph at the 2.6-m Shajn Telescope of the Crimean Astrophysical Observatory in 1988-1995. Total of 202 H{ alpha} region spectra and 154 H{beta} region spectra have formed the data set. A ll spectra were calibrated in flux using the narrow emission lines which were as summed to be constant over the duration of the monitoring program.1997A&A...324..904Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/324/904CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/324/904https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/324/904http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/324/904https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/324/904https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/324/904http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/324/904GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/324/904/table1Cassegrain H-alpha region fluxes (not corrected for seeing effects)recnoRecord number assigned by the VizieR team.
