title = "The broad band spectrum of CYG X-1",
abstract = "We present first results on INTEGRAL and RXTE from our multi-mission observing campaign on Cygnus X-1. The black hole binary Cyg X-1 has been observed simultaneously by INTEGRAL, RXTE, and XMM-Newton for four times in 2004 November and December, when Cyg X-1 became first observable with XMM-Newton (see contribution by Wilms. et al., these proceedings). One of the scientific aims of this campaign was the measurement of a high signal to noise spectrum of Cyg X-1 from 2.5 keV to >600keV in order to constrain models for the hard spectral component We show here first results of our ongoing analysis obtained by modeling the broad band spectrum with simple empirical models as well as with Comptonization models.",
