Einstein IPC Photon Event Data from HEAO-2 Satellite

November 1978 to April 1981 data from the Imaging Proportional Counter aboard the Einstein Observatory (HEAO-2). The database contains photon event lists from a high-resolution X-ray telescope. This is a service provided by NASA HEASARC.

Use Cases

• Analyze X-ray source variability based on photon event timing data.
• Calibrate imaging proportional counter models based on the event list format.
• Study celestial X-ray emissions based on data from the Einstein Observatory's focal plane assembly.

Strengths

• Data originates from the NASA HEASARC, an authoritative source for astrophysics data.
• Covers a defined operational period from launch on November 13, 1978, to end of operations in April 1981.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary file formats are BIN and HTML, which may require specialized tools for analysis.
