EXOSAT Observation Log: Targets, Investigators, and Data Status

A complete list of all observations from the European X-ray Observatory Satellite (EXOSAT). The log includes observed targets, observing modes, principal investigators, and the current state of data analysis. NASA's HEASARC revised the database in August 2005 to modernize parameter names and add Galactic coordinates.

Use Cases

• Identify X-ray astronomical targets observed by the EXOSAT satellite based on the observation log.
• Trace data analysis status and principal investigators for specific EXOSAT observations.
• Study observation modes and instrument usage for the EXOSAT mission.

Strengths

• Described as a complete list of all EXOSAT observations.
• Database was revised in August 2005 to modernize parameter names and add Galactic coordinates.
• Provided by the authoritative NASA HEASARC.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
