NGC 752 X-Ray Point Source Catalog from XMM-Newton Observation

145 X-ray point sources were detected in a 49 ks XMM-Newton observation of the 1.9 Gyr-old open cluster NGC 752. This catalog, created by NASA, includes cross-matches to 2MASS infrared magnitudes and Chandra source numbers, providing data to study stellar activity evolution. The observation was conducted on February 5, 2003, and the derived X-ray luminosities suggest a steep decay in stellar rotation rates around 1 Gyr.

Use Cases

• Modeling stellar rotation decay rates based on X-ray luminosity data mentioned in the description
• Cross-matching multi-wavelength astronomical sources using provided 2MASS and Chandra counterpart identifiers
• Analyzing coronal activity levels in intermediate-age star clusters based on the 1.9 Gyr age of NGC 752
• Comparing X-ray source populations between XMM-Newton and Chandra observations of the same field

Strengths

• Includes cross-matched data from 2MASS and Chandra observations, enhancing multi-wavelength utility
• Observation duration of 49 ks provides a defined sensitivity for the 145 detected point sources
• Specific scientific context provided, including derived X-ray luminosity (1.3 x 10^28 erg s^-1) for cluster members

Limitations

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