Luminosity - Spectral Index Dependence of X-ray Bright Seyfert Galaxies

X-ray luminosities and spectral indices of 97 bright Seyfert 1 galaxies from XMM archive are analyzed in this article. Distribution of these values is random so we conclude that the model of emission should be at least two-parametric. Within the merging model of AGN the relation between black hole mass, stage of merging and observable X-ray parameters is proposed.
