Abstract:
We 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.

Note (1): Instrument and grisms or gratings:
EFOSC = ESO Faint Object Spectrograph and Camera, with the
following possible grisms:
#1: 3400-9200Å; 8.4Å/pix 22Å FWHM resolution
#4: 4650-6800Å; 2.2Å/pix 7Å FWHM resolution
#8: 4640-5950Å; 1.3Å/pix 5Å FWHM resolution
#9: 5875-7020Å; 1.1Å/pix 5Å FWHM resolution
#10: 6600-7820Å; 1.2Å/pix 5Å FWHM resolution
ES2 = McDonald Cassegrain Spectrograph.
Note (2): The file naming conventions are:
=> "sp" followed by the object No, eventually followed by
g4, g8, _g9, or _g10, depending which grism or
_fe2 for FeII subtracted spectra.
=> "fe2_" followed by the object No for the FeII templates
used for the FeII subtracted spectra.
