TUES

Map of Observations

Wavelength Coverage

The Tübingen Echelle Spectrograph (TUES), designed and managed at the University of Tübingen, flew on the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrograph (ORFEUS)-SPAS II space shuttle mission in 1996, returning spectra in the 900 Å to 1400 Å wavelength range. The instrument was designed to achieve a spectral resolution of λ/Δλ =10000 when used with an entrance aperture of 10" diameter. During the 17.7 day flight, TUES returned 239 spectra of 62 targets.
