ROSATPSPCCatalogofLMCX-RaySources(Haberl&Pietsch)

Metadata Updated: April 10, 2026

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 on order to derive a catalogue of X-ray sources. The list contains 758 sources together with their X-ray properties. From cross-correlations of the PSPC catalogue with the SIMBAD data base and literature searches likely identifications are given in the paper from which this catalogue was derived (Haberl & Pietsch 1999, A&AS, 139, 277: Table 10) for 144 of these X-ray sources based on positional coincidence, but also taking into account X-ray properties like hardness ratios and source extent. Forty-six known sources are associated with supernova remnants and candidates in the LMC (SNRs: Haberl & Pietsch 1999, A&AS, 139, 277: Table 6), most of them already detected by previous X-ray missions. The number of known X-ray binaries in the LMC has increased to 17, and of supersoft sources to 9. The remaining ~50% of the identified sources comprise mainly foreground stars (up to 57) and background extragalactic objects (up to 15). This database was created at the HEASARC in June 2000 based on the ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+AS/139/277">CDS Catalog J/A+AS/139/277</a>, and is derived from Table 1 of the reference. This is a service provided by NASA HEASARC .
