Performance of the space telescope imaging spectrograph

The Space Telescope Imaging Spectrograph (STIS) was installed aboard the Hubble Space Telescope (HST) in February, 1997. STIS operates from the ultraviolet to the near infrared (115–1000 nm) in a variety of spectroscopic and imaging modes. Orbital characterization of STIS performance is currently underway and some of the initial results are presented here.
