International Ultraviolet Explorer: Over 104,000 Spectra from 1978-1996

Over 104,000 ultraviolet spectra were obtained by the International Ultraviolet Explorer (IUE) satellite between January 26, 1978, and September 30, 1996. The data provides spectrophotometry at high (0.1-0.3 Å) and low (6-7 Å) resolution across wavelengths from 1150 Å to 3200 Å. This dataset was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Analyze stellar atmospheric composition based on high-resolution ultraviolet spectra.
• Study temporal variability in celestial objects based on the 18-year observation period.
• Train spectral classification models based on the wavelength range from 1150 Å to 3200 Å.
• Calibrate or validate other ultraviolet observational data based on the defined dynamic range of astronomical magnitudes.

Strengths

• Over 104,000 individual spectra provide a substantial observational record.
• Covers an 18-year time range from 1978 to 1996, enabling long-term studies.
• Data includes both high and low resolution measurements across a defined ultraviolet wavelength range.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific operational period of the IUE satellite.
