About 60% of them are spectroscopically identified Type 1 AGN, while the others have a reliable photometric redshift and are classified as Type 1 AGN on the basis of their multi-band Spectral Energy Distributions. We discuss the relationship between UV and X-ray luminosity, as parameterized by the alphaox spectral slope, and its dependence on redshift and luminosity. Description: Optical and X-ray properties for 545 Type 1 AGN in XMM-COSMOS are presented. For each source, X-ray ID, spectroscopic redshift, photometric redshift, upper error on the photometric redshift, lower error on the photometric redshift, logarithm of the monochromatic luminosity al 2500Å, logarithm of the monochromatic luminosity at 2keV, alphaox, logarithm of the 2-10keV luminosity, logarithm of the bolometric luminosity in solar units, bolometric correction, photometric classification, logarithm of the Eddington ratio, logarithm of the black hole mass in 109 solar masses, flag for the 2-10keV detection (flag=1 [343 entries] means a detection in the 2-10keV band, while flag=0 is for 2-10keV upper limits).
