GHRS Instrument Science Report 043 Cycle 1 Detector Calibrations 10/92 Stephen J. Hulbert Abstract excerpted from the report: The GHRS detector calibration program (Proposal 3298) was executed in Cycle 1 to monitor the GHRS detector 2. Detector 1 was not monitored; it is currently unavailable due to hardware problems. The behavior of detector 2 was nominal during the cycle and continues to be stable at the SV-measured levels.
