J/A+AS/143/391      ROSAT HRI catalogue of LMC X-ray sources    (Sasaki+, 2000)

ROSAT HRI catalogue of X-ray sources in the LMC region Sasaki M., Haberl F., Pietsch W. <Astron. Astrophys. Suppl. Ser. 143, 391 (2000)> =2000A&AS..143..391S
ADC_Keywords: X-ray sources ; Magellanic Clouds Keywords: catalogues - galaxies: Magellanic Clouds - galaxies: stellar content - X-rays: galaxies - X-rays: stars Description: The ROSAT HRI LMC source catalogue is based on all 543 pointed observations of the ROSAT HRI between 1990 and 1998 with exposure times higher than 50 sec. The observations covered a 10 deg x 10 deg field including the LMC. The catalogue contains 397 X-ray sources. Sources showing flux variability in ROSAT HRI and PSPC are listed in Table 1. Table 2 contains HRI sources which were identified with known objects in other catalogues and literature. Table 3 is a list of new classifications. The whole source catalogue from HRI observations is given in Table 4. File Summary:

Note (1): For sources which are listed in the ROSAT PSPC catalogue (Haberl & Pietsch, 1999, Cat. J/A+AS/139/277) PSPC count rates are taken from the catalogue. Otherwise PSPC count rate is the 2 sigma upper limit from maximum likelihood algorithm ('<' in column Uplim).
