Confirming previous analyses, we find robust evidence for a broad iron line associated with X-ray reflection from the innermost accretion disk. By fitting a spectral model that includes a relativistically ionized reflection component, we examine the constraints on the inclination of the inner accretion disk and the black hole spin, and the complications introduced by the presence of a photoionized emission line system. Employing multi-epoch fitting, we attempt to obtain robust and","authors_text":"Andrew C. Fabian, Anne M. Lohfink, Christopher S. Reynolds, Jon M. Miller, Laura W. Brenneman, Michael A.
