NGC 2547 X-Ray Point Source Catalog from XMM-Newton

XMM-Newton EPIC detected X-ray emission from stars at all spectral types in the young open cluster NGC 2547, peaking among G stars at luminosities of ~10^30.5 erg/s. This table contains properties of X-ray sources correlated and uncorrelated with optical cluster members, including cross-identifications, luminosities, and flux ratios. The HEASARC created this catalog in February 2007 based on CDS files from a reference paper.

Use Cases

• Analyze coronal activity levels in solar-type stars based on X-ray luminosity and Lx/Lbol ratios.
• Compare X-ray emission characteristics across different spectral types (G to M stars) mentioned in the description.
• Study the evolution of stellar X-ray activity by comparing data from NGC 2547 with older clusters like the Pleiades.
• Correlate X-ray point sources with optical cluster members using the cross-identification data.

Strengths

• Data originates from the XMM-Newton EPIC instrument, a major space observatory.
• Includes correlations with optical catalogs and comparisons with earlier ROSAT HRI observations.
• Catalog created and served by NASA's HEASARC, an authoritative astrophysics data center.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
