GHRS Instrument Science Report 058 "An Assessment of the Pipeline Wavelength Calibrations for the Side 2 Echelle Grating of the GHRS (Ech-B) in Cycles 2 and 3" David R. Soderblom, Lisa E. Sherbert, and Stephen J. Hulbert Abstract excerpted from the report: In Cycles 2 and 3 of the HST science program several programs were executed to monitor the behavior of the GHRS. Among these are tests of the stability of the wavelength scales for the various gratings. The results for the first-order gratings were reported in GHRS ISR 52; this Instrument Science Report discusses measurements for the echelle grating on Side 2, known as Echelle-B.
