Beginning of ReadMe : J/A+A/388/100 ROSAT X-ray sources in LMC. II. (Kahabka, 2002) ================================================================================ ROSAT X-ray sources in the field of the LMC. II. Statistics of background AGN and X-ray binaries Kahabka P. <Astron. Astrophys. 388, 100 (2002)> =2002A&A...388..100K ================================================================================ ADC_Keywords: X-ray sources ; Magellanic Clouds ; Surveys Keywords: catalogues: Magellanic Clouds - galaxies: individual: LMC - galaxies: active - galaxies: ISM - X-rays: galaxies - X-rays: stars Abstract: About 200 X-ray sources from a sample of spectrally hard ROSAT PSPC sources, given in the catalog of Haberl & Pietsch (1999, Cat. J/A+AS/139/277), and observed in a  60 square degree field of the LMC during several archival pointed observations with a wide range of exposure times have been reanalyzed. For these sources accurate count rates and hardness ratios have been recalculated. In comparison to Haberl & Pietsch (1999, Cat. J/A+AS/139/277) we used merged data from all available observations and we derived average source parameters by investigating each source individually. From a simulation power-law spectral tracks have been derived in the HR1-HR2 plane and  170 sources have been classified as background X-ray sources or as LMC X-ray binaries. 80% of the spectrally hard X-ray sources with more than 50 observed counts have been found to be consistent with background X-ray sources and 20% with LMC X-ray binaries (53 sources with AGN and 15 with X-ray binaries).
