Iron line region from 6–9 keV, where absorption features are clearly seen. The various panels represent observations for three different epochs. Black crosses show the data, dotted black lines represent atm model, while solid red lines show the total model. Upper panels show the disk seen at i = 11 ± 5°, whereas lower panels show the disk seen at i = 70 ± 6°. All spectra favor fitting for i = 11 ± 5°, since modeled lines are the deepest for this model.
