... We obtained a high signal to noise spectrum of Cyg X-1 from 3 keV to 1 MeV which allows us to put constraints on the nature of the Comptonizing plasma by modeling the continuum with Comptonization models as eqpair [3]. ... Further spectral characteristics are reflection features from the accretion disk and a relativistically broadened Fe K emission line at about 6.4 keV. ... IRON LINE 3.1. ... SUMMARY AND OUTLOOK The 3 keV­1 MeV broadband spectrum of Cyg X-1 can be well described by the eqpair model...
