International Ultraviolet Explorer
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. 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.
