Einstein HRI: High-Resolution X-ray Photon Event Data from 1978-1981

November 1978 to April 1981 photon event data from the Einstein Observatory's High Resolution Imager (HRI). The database contains information from the HEAO-2 satellite's X-ray telescope in Event List Format. This is a service provided by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC).

Use Cases

• Analyze X-ray photon arrival times and positions based on the event list format.
• Study celestial X-ray sources based on data from the high-resolution imaging detector.
• Cross-reference observations with other Einstein Observatory instruments based on the described focal plane assembly.
• Conduct temporal analysis of X-ray emissions based on the defined operational period.

Strengths

• Data originates from a NASA satellite mission with a defined operational period from November 1978 to April 1981.
• Provided by NASA HEASARC, an authoritative archive for high-energy astrophysics data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in BIN format, which may require specialized tools for access and processing.
