XMM-Newton Master Log: Catalog of Completed and Scheduled Observations

NASA HEASARC's master catalog lists all completed and near-future scheduled observations from the XMM-Newton X-ray observatory, including data from spacecraft slews. The table is periodically updated from information supplied by the XMM-Newton Project and includes entries where the proprietary period has expired, though some data may be hosted by the ESA archive. This service is provided by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC).

Use Cases

• Querying the observation history of the XMM-Newton telescope based on parameters like observation ID and public date.
• Identifying upcoming scheduled observations for planning complementary scientific studies.
• Differentiating between pointed observations and slew data based on observation ID prefixes.
• Verifying data availability between the HEASARC and ESA archives using the data_in_heasarc flag.

Strengths

• Includes both completed observations and those scheduled for the near future (typically a few weeks to a month ahead).
• Distinguishes between pointed observations and slew data, which lack fixed positional coordinates.
• Periodically updated within days of modifications to the source project URLs.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Does not contain observations scheduled far in the future or accepted but unscheduled observations.
