GHRS Instrument Science Report No. 90 "Redetermination of Sensitivity for Echelle-B" J. R. Mack, L. E. Sherbert, D. R. Soderblom September 25, 1997 Abstract This ISR describes a complete redetermination of the GHRS sensitivity for the Echelle-B grating. The procedures used to derive the corrected sensitivity functions are described here, and new files have been installed in the CDBS.
