The Space Telescope Imaging Spectrograph (STIS) was installed in HST on 1997-Feb-14, replacing the GHRS spectrograph. On 2004-Aug-03, STIS stopped science operations and is currently in "safe" mode. During its operations, STIS provided scientists with spectra and images at ultraviolet and visible wavelengths, probing the Universe from our solar system out to cosmological distances.
This website provides information needed to analyze archival STIS data. Feedback or requests for more information should be sent to the Help Desk.
