2004AJ....127..156G A Complete Sample of Soft X-Ray - selected AGNs. I. The Data Dirk Grupe, Beverley J. Wills, Karen M. Leighly, and Helmut Meusinger Abstract. We present the optical spectra and simple statistical analysis for a complete sample of 110 soft X-ray - selected AGNs. About half of the sources are narrow-line Seyfert 1 galaxies (NLS1's), which have the steepest X-ray spectra, the strongest Fe II emission, and slightly weaker [O III] {lambda}5007 emission than broad-line Seyfert 1's (BLS1's). Kolmogorov-Smirnov tests show that NLS1's and BLS1's have clearly different distributions of the X-ray spectral slope {alpha}_X_, X-ray short-term variability, and Fe II equivalent widths and luminosity and Fe II/H{beta} ratios. The differences in the [O III]/H{beta} and [O III] equivalent widths are only marginal. We found no significant differences between NLS1's and BLS1's in their rest-frame 0.2 - 2.0 X-ray luminosities, rest-frame 5100 monochromatic luminosities, bolometric luminosities, redshifts, and their H{beta} equivalent widths. Keywords: Galaxies: Active, Galaxies: Quasars: General
