We report on the analysis of the broad Fe K \alpha line feature of Cyg X-1 in the spectra of four simultaneous hard intermediate state observations made with the X-ray Multiple Mirror mission ( XMM-Newton ) , the Rossi X-ray Timing Explorer ( RXTE ) , and the International Gamma-Ray Astrophysics Laboratory ( INTEGRAL ) . The high quality of the XMM-Newton data taken in the Modified Timing Mode of the EPIC-pn camera provides a great opportunity to investigate the broadened Fe K \alpha reflection line at 6.4 keV with a very high signal to noise ratio . The 4–500 keV energy range is used to constrain the underlying continuum and the reflection at higher energies . We first investigate the data by applying a phenomenological model that consists of the sum of an exponentially cutoff power law and relativistically smeared reflection . Additionally , we apply a more physical approach and model the irradiation of the accretion disk directly from the lamp post geometry . All four observations show consistent values for the black hole parameters with a spin of a \sim 0.9 , in agreement with recent measurements from reflection and disk continuum fitting . The inclination is found to be i \sim 30 \degr , consistent with the orbital inclination and different from inclination measurements made during the soft state , which show a higher inclination . We speculate that the difference between the inclination measurements is due to changes in the inner region of the accretion disk .
