The Goddard High-Resolution Spectrograph (GHRS) was one of the 4 original axial instruments aboard the Hubble Space Telescope (HST). The GHRS was designed to take spectral observations of astrophysical sources from 1150 to 3200 Angstroms. The instrument was removed from HST during Servicing Mission 2 in February, 1997.

These pages present documentation and calibration resources for researchers interested in using archival GHRS data.
