ROSAT PSPC Catalog of LMC X-Ray Sources (1990-1994)

More than 200 ROSAT PSPC observations performed between 1990 and 1994 in a 10 by 10 degree field centered on the Large Magellanic Cloud (LMC) have been analyzed to derive a catalogue of X-ray sources. The list contains 758 sources together with their X-ray properties, with likely identifications provided for 144 sources. This database was created at the NASA HEASARC in June 2000 based on the ADC/CDS Catalog J/A+AS/139/277.

Use Cases

• Classifying X-ray source types based on hardness ratios and source extent mentioned in the description.
• Cross-matching catalog positions with other astronomical databases for source identification.
• Studying populations of supernova remnants and X-ray binaries in the Large Magellanic Cloud.
• Analyzing the distribution and properties of foreground stars and background extragalactic objects detected in X-rays.

Strengths

• Contains 758 X-ray sources with associated properties.
• Provides likely identifications for 144 sources, including 46 associated with supernova remnants.
• Derived from more than 200 observations over a defined 1990-1994 time period.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the 1990-1994 observation window.
