Berkeley Extreme and Far-UV Spectrometer
The Berkeley Extreme and Far-UV Spectrometer (BEFS),
flew on the Orbiting and
Retrievable Far and Extreme Ultraviolet Spectrograph (ORFEUS)-SPAS
I and II space shuttle missions in 1993 and 1996, returning high-resolution
(/3000) FUV spectra
(900-1200 Å)
of 75 astrophysical objects from the first flight and more than 100 from
the second. EUV spectra (400-900 Å) were obtained for a subset of these
targets.
