X-ray spectra of Hercules X-1. 2. Intrinsic beam. [2 to 24 keV, spectral correlations]

Technical Report ·
OSTI ID:7290851
; ; ;
The X-ray spectrum of Hercules X-1 was observed in the energy range 2-24 keV with sufficient temporal resolution to allow detailed study of spectral correlations with the 1.24 sec pulse phase. A region of spectral hardening which extends over approximately the 1/10 pulse phase may be associated with the underlying beam. The pulse shape stability and its asymmetry relative to this intrinsic beam are discussed.
