The Goddard High Resolution Spectrograph (GHRS) is an ultraviolet spectrograph developed by the Goddard Space Flight Center and constructed by the Ball Aerospace Systems Group. The basic performance characteristics are given in Table 1. The detectors are Digicons with an approximately 500-diode linear array; the faceplate/photocathode combinations are LiF/CsI for Side 1 and MgF2/CsTe for Side 2. The two science apertures are 2x2 and 0.25 x 0.25 arc seconds square. The GHRS has several undispersed-light modes for target acquisition.
