Copernicus wavelength coverage plot

The Copernicus satellite, known initially as the Orbiting Astrophysical Observatory 3), obtained high-resolution spectra in the far- and near-ultraviolet of 551 UV sources, mostly bright stars. The satellite also featured an X-ray experiment, the data for which are hosted at HEASARC. The Copernicus mission was a collaboration between NASA and the SERC of the United Kingdom, and was operated by Princeton University (PI: Lyman Spitzer).
