High energy X-ray spectrum of Her X-1Line features in the high-energy X-ray spectrum of Her X-1 are attributed to an approximately 1% change in detector gain. The spectrum was obtained by a high-energy X-ray detector aboard OSO-8. The time-averaged spectrum of Her X-1 for the period August 31-Sept. 6, 1977 is presented; the count-rate spectrum was corrected for an average change in gain of 0.7%. The best fit power-law is reported.
