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.
