Large Magellanic Cloud X-Ray Sources Catalog

NASA HEASARC provides a catalog of Einstein IPC X-ray sources in the Large Magellanic Cloud. The table contains 105 discrete and 9 large-diameter sources, as tabulated by Wang et al. (1991). Full data processing details are available in the referenced astrophysical publication.

Use Cases

• Cross-match discrete source positions with other LMC catalogs to study multi-wavelength counterparts.
• Analyze the spatial distribution of the 9 large-diameter sources relative to LMC structures.
• Validate source detection algorithms using the selection criteria from Wang et al. (1991) for compact and extended objects.

Strengths

• Catalog is derived from a peer-reviewed publication in The Astrophysical Journal (Wang et al., 1991).
• Contains a specific count of 105 discrete and 9 large-diameter X-ray sources.
• Data is served by the authoritative NASA HEASARC archive.

Limitations

• Sample size is limited to 114 total sources from a single instrument.
• Data is from 1991 and may not reflect more recent X-ray observations.
• Column definitions and sample data are unavailable, limiting immediate analysis.
