Lockman Hole XMM-Newton X-Ray Point Source Catalog with Spectral Analysis

A 2007 catalog from NASA HEASARC contains detailed X-ray spectral analysis for 123 sources detected by XMM-Newton in the Lockman Hole field. The analysis is based on over 600 ks of good EPIC-pn data, representing the deepest XMM-Newton observation at the time. Optical spectroscopic identifications were available for 60% of the sources, including 46 type-1 and 28 type-2 AGN.

Use Cases

• Analyze the spectral slope hardening trend at faint 0.5-2 keV fluxes based on the single power law model results.
• Study the population of optical type-1 and type-2 AGN identified in the X-ray source sample.
• Benchmark source detection and spectral properties against the deep 600 ks XMM-Newton EPIC-pn exposure.
• Investigate flux limits and source counts in specific energy bands (0.2-12 keV, 0.5-2 keV, 2-10 keV).

Strengths

• Spectral analysis is based on a deep observation with over 600 ks of good EPIC-pn data.
• Contains 123 X-ray sources with spectra having good signal-to-noise (>500 source counts).
• Optical spectroscopic identifications are provided for 60% of the sources (74 objects).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data was created in June 2007; freshness should be verified for current research.
