Abstract:
We have produced an archive of the ultraviolet low-dispersion spectra
for the full set of white dwarf stars observed with the International
Ultraviolet Explorer (IUE) satellite over the course of its 18-yr
mission. This archive contains the spectra of 322 individual
degenerate stars which have been processed to optimize the signal-to-
noise for each star. In particular, all spectra have been corrected
for residual temporal and thermal effects and placed on the Hubble
Space Telescope Faint Object Spectrograph absolute flux scale using
procedures described by Massa & Fitzpatrick (2000ApJS..126..517M 2000ApJS..126..517M).
Wherever possible, multiple observations of individual stars have been
co-added to further enhance signal-to-noise and have been combined
into a single spectrum including the full 1150 to 3150Å wavelength
region observed by IUE. The contents of this spectral archive are
described and the details of data reduction procedures are provided.
The electronic files of the processed spectra are available, in FITS
and ASCII formats, with the associated log file, at

SWP = short wavelength prime
SWR = short wavelength redundant
LWP = long wavelength prime
LWR = long wavelength redundant
SAP = circular small aperture, 3" in diameter
LAP = large aperture with a rectangular oval shape of 10"x20"
