NGC 1512/NGC 1510 X-Ray Point Source Catalog from XMM-Newton

106 X-ray point sources detected in the interacting galaxy pair NGC 1512/NGC 1510 by the XMM-Newton space telescope. The catalog was produced by NASA using a single 63-ks observation on 2012 June 16-17, with sources classified via spectral analysis and cross-correlation with optical, infrared, and radio catalogs. It includes 15 sources within the galaxies' D25 regions and characterizes diffuse emission from NGC 1512.

Use Cases

• Classifying X-ray source types (e.g., foreground stars, background objects, high-mass X-ray binaries) based on spectral analysis and hardness ratios.
• Correlating X-ray source properties with star formation rates in interacting galaxies, as referenced in the description.
• Studying diffuse X-ray emission from galaxy interiors using the reported plasma temperature and luminosity.
• Analyzing source variability and cross-matching with multi-wavelength catalogs (optical, infrared, radio) for identification.

Strengths

• Contains 106 detected sources in the 0.2-12 keV energy range, providing a substantial sample for analysis.
• Sources are classified using multiple methods: spectral analysis, Bayesian hardness ratios, variability, and cross-correlation with other wavelength catalogs.
• Includes specific measurements for diffuse emission: plasma temperature of kT = 0.68 keV and luminosity of 1.3E+38 erg/s.
• Utilizes data from multiple instruments (PN, MOS1, MOS2) across five defined energy bands.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment and require field semantics to be inferred after download.
• The observation was contaminated by high background proton flares, reducing net good exposure time to between 26.0 and 39.8 ks per instrument.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
