Relations between the IR-UV-X-ray continuum and emission lines for a largecomposite sample of narrow line and normal Seyfert 1 galaxies

We report on our research on the UV, optical line parameters and the infrar ed through UV to soft X-ray continuum parameters for a composite sample of narrow line and normal Seyfert 1 galaxies. The strong correlations among th e line width of H beta, optical line strength of FeII and the soft X-ray sl ope are confirmed. We found no correlations between the UV line parameters, the equivalent widths of Ly alpha and CIV and their ratio on one hand and the optical line parameters on the other. The UV and X-ray luminosities str ongly correlate with the line widths of H beta and the Fe II/H beta ratio. No significant correlation is found between the infrared-soft X-ray continu um slope alpha (ix) and the line width of H beta.
