Extended downtime notice
Due to a planned outage on Friday, April 12th starting at noon through
Sunday, April 14th, access to this site will be unavailable during this
time. We apologize for any inconvenience.
The Extreme Ultraviolet Explorer (EUVE) was the first satellite
entirely dedicated
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.
