NGC 1600 Chandra X-Ray Discrete Source Catalog: 71 Detected Sources

NASA's Chandra X-Ray Observatory catalog of 71 discrete X-ray sources detected in observations of the E3 galaxy NGC 1600 and its group. The data includes 21 ultraluminous X-ray point source candidates and was collected in two observations on September 18-20, 2002. The authors propose many unresolved sources are associated with globular clusters.

Use Cases

• Identifying ultraluminous X-ray point source candidates based on luminosity thresholds (>2e39 ergs/s).
• Analyzing the luminosity function and spectral properties of X-ray sources in early-type galaxies.
• Studying the correlation between X-ray sources and globular cluster populations in galaxies.
• Estimating foreground and background source contamination using established source count models.

Strengths

• Contains 71 discrete X-ray sources with detailed positional and photometric data.
• Identifies 21 sources as ultraluminous X-ray point source candidates based on a defined luminosity threshold.
• Observations were filtered for background flares, providing flare-free exposure times of 21,562 and 23,616 seconds.
• Source detection performed with wavdetect over the 0.3-6 keV energy range.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The authors note cosmic variance in the number of background active galactic nuclei cannot be ruled out.
