GHRS Instrument Science Report 041 "Cycle 1 Dark Noise Monitoring" 9/92 Stephen J. Hulbert, Lisa E. Walter, and Jonathan D. Eisenhamer Abstract excerpted from the report: The GHRS dark noise monitoring calibration program (2841) was executed five times during Cycle 1. Dark count response continues to be nominal for Detector 2: the average background count rate was 0.011 counts s-1 diode-1. Detector 1 was not monitored due to the Side 1 hardware failure.
