XMMSL3: XMM-Newton Slew Survey Full Source Catalog, 2000-2023

140,735 X-ray source detections from the European Space Agency's XMM-Newton Observatory, covering an energy interval from 0.2 keV to 12 keV. The XMM-Newton Survey Science Center created this third catalog (XMMSL3) based on 3,120 public slew observations made between 2000 August 26 and 2023 August 11. NASA's HEASARC ingested and hosts the table, which contains 68,383 more detections than the previous version.

Use Cases

• Identify and catalog celestial X-ray sources based on detection data.
• Analyze temporal changes in X-ray source behavior across a 23-year observation period.
• Cross-match X-ray detections with other electromagnetic waveband catalogs.
• Study the statistical properties of the X-ray source population detected in slew mode.

Strengths

• Contains 140,735 X-ray detections, a significant increase from the previous catalog.
• Covers 23 years of observations (2000-2023), providing long-term temporal coverage.
• Based on 3,120 individual observations, a 50% increase from the prior version.
• Data is publicly available and sourced from a major space observatory (ESA's XMM-Newton).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
