J/A+A/400/521       Omega Cen XMM observations                   (Gendre+, 2003)

An XMM-Newton observation of the globular cluster Omega Centauri. Gendre B., Barret D., Webb N.A. <Astron. Astrophys. 400, 521 (2003)> =2003A&A...400..521G
ADC_Keywords: Clusters, globular ; X-ray sources Keywords: globular clusters: individuals (Omega Centauri) - X-ray: binaries - stars: neutron - novae, cataclysmic variables - binaries: general Description: We have observed the globular cluster Omega Cen (NGC 5139) with XMM-Newton on August 13th, 2001. The observation lasted 37ks and was performed with a medium filter. These tables list all the detected sources, and the spectral properties of selected sources within the field of view. For each source, we indicate its position, count rate, correlation with previous X-ray observation, and associated errors. For selected sources we also indicate its flux. File Summary:

Note (1): We have indicated in this table only the sources correlated with other X-ray observations. There are three OGLEGC sources which are associated with X-ray sources (OGLEGC 15 and 22 with two Chandra sources, OGLEGC 30 with XMM-Newton source 29). Their positions from Kaluzny et al., 1996, Cat. J/A+AS/120/139 are: OGLEGC15 13h 26min 47.42s -47° 36' 00.4" OGLEGC22 13h 26min 08.33s -47° 30' 33.0" OGLEGC30 13h 26min 53.33s -47° 18' 22.9"-------------------------------------------------------------------------------- Byte-by-byte Description of file: table5.dat
