Scientific paper

This ISR describes a redetermination of the GHRS sensitivity functions for the Echelle-A and G140M gratings. Changes amount to ~20% for Echelle-A over the entire range of wavelengths, compared to the previous values. G140M also deviates slightly from the reference spectrum and requires a linear correction with wavelength, amounting to ~2% at 1100A and 8% at 1600A. The procedures used to derive the corrected sensitivity func tions are described here, and new files have been installed in the CDBS.
