cds-question@unistra.fractive-galactic-nucleiquasarsspectroscopyWe present the emission line properties of a sample of 76 bright soft X-ray selected ROSAT Active Galactic Nuclei. All optical counterparts are Seyfert 1 galaxies with rather narrow permitted lines, strong optical FeII line blends, and weak forbidden lines. By selection, they also have steep soft X-ray spectra when compared with typical Seyfert 1 galaxies. We discuss possible origins of these peculiar trends employing detailed correlation analyses, including a Principal Component Analysis. The optical spectra are presented in the Appendix.1999A&A...350..805Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/350/805CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/109/147 : ROSAT AGN content (Brinkmann+, 1995)J/A+AS/110/469 : AGN from the RASS (Bade+, 1995)J/A+A/323/739 : ROSAT detected quasars.
