GHRS Instrument Science Report 052 "An Assessment of the Pipeline Wavelength Calibrations for the First Order Gratings of the GHRS in Cycle 2" David R. Soderblom, Lisa E. Sherbert, and Stephen J. Hulbert Abstract excerpted from the report: This Report is based on several executions of calibration proposal 4067 and shows that the default wavelength scaled provided by the pipeline data reduction system has not changed significantly with time. WAVE exposures as part of user observations can, however, improve the zero point for each observation, as can use of SPYBAL exposures.
