The Extreme Ultraviolet Explorer (EUVE) was the first satellite
to the Extreme Ultraviolet (EUV) band of the spectrum (70 -760 Å).
Launched June 7, 1992, EUVE conducted an all-sky survey that detected over
900 objects. The 6 month survey portion of the mission was followed by 8 years
of pointed spectroscopic observations of over 350 objects. The EUVE
instrumentation included the Deep Survey (DS) imager and 3 spectrometers.
One-half of the light falling in the telescope was focused on the DS and
the remaining half was intercepted by one the the spectrometers. The short
wavelength spectrometer covered 70-190 Å, the medium wavelength
spectrometer covered 140-380 Å, and the long wavelength spectrometer
covered 280-760 Å. The resolving power was 260 in each spectrometer. The
data from the 3 all-sky survey telescopes ("scanners") is not archived here.
The available data products for the EUVE spectrometers and Deep Survey
instruments are stored in two different formats: 1) Binary FITS tables that
include time-tagged events for temporal analysis (e.g. light-curves) and
2) 2-D FITS images of the DS and spectrometers. All 4 instruments are stored
in a single FITS file with 4 extensions. The reductions that produced the 2-D
images are expected to fill the needs of most users, but these can be
re-extracted from the FITS tables. EUVE data resides at HEASARC,
but are also available through MAST.
