STScI will be down completely for electrical
work from 2:00 PM Friday, 2 December – 6:00 AM Monday, 5 December, 2016.
Mail will be queued and delivered after the work is completed,
but there may be a delay. DADS and data processing won't be up until
some time Monday morning. Our apologies for the inconvenience.
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
/=10000 when used with
an entrance aperture of 10" diameter.
During the 17.7 day flight, TUES returned 239 spectra of 62 targets.
