OAO-3 "Copernicus" High Resolution Spectral Atlases
During the Copernicus mission several stars were observed
intensively with the high-resolution spectrometers to obtain as complete
wavelength coverage as possible. Ultraviolet high resolution spectral
atlases were constructed for six stars: Alpha CMa (Sirius), Alpha Lyr
(Vega), Beta Ori (Rigel), Gamma Peg, Iota Her, and Tau Sco.
The atlas data were delivered to GSFC by the Copernicus Project at
Princeton University in the early 1980s. The data are now available in
FITS binary table format and can be selected from the following table.
Each star also has a corresponding journal article describing the details
of the extraction and analysis, including identification of spectral
features. Summary information on the atlas contents and file descriptions
are included on the pages for each atlas.

The files may be read with any FITS reader that supports the binary table
format. The IUEDAC procedure IFITSRD is a generic IDL based FITS reader
which can be used to read these files.
