Cyg X-1 during an X-ray intermediate state (about 40 RXTE/ASM counts per sec) as determined by Melissa Warstadt July 26, 2007.
Composite close-up of the X-ray region. The hard-state spectrum observed by Ginga and OSSE on 1991 June 6 (Gierlin'ski et al. 1997, MNRAS, 309, 958) and by COMPTEL 1991 May 30--June 8 (McConnell et al. 1994, ApJ, 309, 933). The intermediate state observed by RXTE on 1996 May 23. The soft state observed by ASCA and RXTE on 1996 May 30 and by OSSE 1996 June 14--25. The curves correspond to the hybrid model from Gierlin'ski et al. 1999, MNRAS, 309, 496.
