The International Ultraviolet Explorer (IUE) performed spectrophotometry at high (6-7 Å) and low (0.1-0.3 Å) resolution between 1150 Å and 3200 Å. The data cover a dynamic range of approximately 17 astronomical magnitudes: -2 to 10 for high dispersion; -2 and 14.9 for low dispersion. Over 104,000 ultraviolet spectra were obtained with IUE between January 26, 1978, and September 30, 1996.
