X-ray reflection features observed from the innermost regions of accretion disks in Active Galactic Nuclei (AGNs) allow important tests of accretion theory. In recent years it has been possible to use the Fe K line and reflection continuum to parametrize the ionization state of the irradiated inner accretion disk. Here, we collect 10 measurements of xi, the disk ionization parameter, from 8 AGNs with strong evidence for reflection from the inner accretion disk and good black hole mass estimates… Expand
