Chandra X-Ray Point Source Catalog for the Small Magellanic Cloud Wing

523 X-ray sources detected in the Small Magellanic Cloud Wing by the Chandra X-ray Observatory between July 2005 and March 2006. The catalog includes positional data, photon energy distribution metrics, and flux for all sources, with preliminary classifications for 265 objects based on cross-correlation with optical and infrared catalogs. This table was created by NASA's HEASARC in June 2008 based on the CDS Catalog J/MNRAS/383/330.

Use Cases

• Classifying X-ray source types (e.g., pulsars, AGN, stars) based on X-ray colors and flux ratios mentioned in the description.
• Studying the distribution and properties of high-mass X-ray binary candidates in the Small Magellanic Cloud.
• Cross-matching celestial objects across electromagnetic spectra using provided equatorial coordinates and optical counterpart data.
• Analyzing the photon energy distribution of sources using the provided median, compressed median, and normalized quartile ratio metrics.

Strengths

• Contains data for 523 detected X-ray sources with positional errors, net counts, and signal-to-noise metrics.
• Provides preliminary classifications for 265 objects, including 4 pulsars, 34 stars, and 185 active galactic nuclei.
• Based on observations from 20 Chandra fields with controlled exposure times ranging from 8.6 to 10.3 ks.

Limitations

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