cds-question@unistra.frseyfert-galaxiesspectroscopyultraviolet-astronomyThis is a study of the UV variability of the galaxy Fairall-9 between 1978 and 1991. Table 1 shows the UV continuum fluxes measured in three "line-free" windows centered at 1171, 1400 and 1910 A (observed wavelengths), and corrected for E(B-V)=0.035 extinction. The IUE Fine Error Sensor (FES) counts (optical photometry) are also given in this table, corrected for the same extinction. Tables 10, 11, 12 and 13 show the variability of the components for the main UV lines (Ly{alpha}+NV, SiIV, CIV and MgII). Line profile variability has been used to isolate four gaussian line components, which are sufficient to describe all lines at all levels of brightness in a consistent way: one narrow (i.e. unresolved at the IUE resolution) and three broad components: a central (velocity same as the narrow line), a redshifted (v=3300 km/s) and a blue shifted one (v=-3600 km/s). The Ly{alpha}-NV blend is fitted together in the Ly{alpha} region (Table 10), to account the NV presence (one narrow and one red component). The results for SiIV are shown in Table 11. In CIV (Table 12) have been included a very weak component bluer than the blue component, most likely associated with NIV] 1486. Table 13 shows MgII results.1997A&AS..121..461Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/121/461CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/121/461https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/121/461http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/121/461https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/121/461https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/121/461http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/121/461GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapUVdefaultJ/A+AS/121/461/table11SiIV lambda 1397 componentsrecnoRecord number assigned by the VizieR team.
