IUE (International Ultraviolet Explorer) Final Merged Observation Log

Published by High Energy Astrophysics Science Archive Research Center | National Aeronautics and Space Administration | Metadata Last Checked: February 21, 2026 | Last Modified: 2026-02-17
This IUE (International Ultraviolet Explorer) Observation Log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at VILSPA. It was constructed by using verified data from the IUE Final Archive Master Catalog. The observations cover the whole life of the IUE satellite, from March 1978 to September 1996. This online catalog was ingested by the HEASARC in August 2004 based on the machine-readable table VI/110/inescat.dat obtained from the CDS data center. In May 2020, the program_id values of "\" were changed by the HEASARC to nulls for improved database compatibility. This is a service provided by NASA HEASARC .
