IC 10 X-Ray Point Source Catalog from XMM-Newton and Chandra Observations

73 XMM-Newton and 28 Chandra detections of point-like X-ray sources in the starburst galaxy IC 10, with observations from 2003. The catalog was created by the HEASARC in October 2011 based on source files from the CDS.

Use Cases

• Identify and classify X-ray point sources based on luminosity and variability data.
• Cross-match X-ray sources with infrared counterparts using the 2MASS catalog positions.
• Study the brightest source X-1 based on its high luminosity and temporal variation factor.
• Analyze the population of foreground stellar objects in the Milky Way due to the low Galactic latitude.

Strengths

• Contains 73 XMM-Newton and 28 Chandra detections, providing a multi-instrument view.
• Includes detailed observation parameters, such as exposure times of ~45 ks and ~42 ks for specific cameras.
• Provides cross-correlation with the 2MASS catalog using defined matching radii (4 arcsec and 2 arcsec).
• Specific luminosity data for source X-1 (~1.2E38 erg s⁻¹) and variation factor (~6) are included.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• A substantial fraction of sources are likely foreground Milky Way objects, which may complicate analysis of IC 10's intrinsic population.
