IUE Archive ( MAST )

The International Ultraviolet Explorer (IUE) performed spectrophotometry at high (0.1-0.3 Å) and low (6-7 Å) resolution between 1150 Å and 3200 Å.
Over 104,000 ultraviolet spectra were obtained with IUE between January 26, 1978, and September 30, 1996.
This is part of the Multimission Archive at STScI.
