Table 1: List of sources that are detected in the area covered by the Cartwheel system and displayed in Fig. 1. Unabsorbed fluxes are computed in the 0.5-2 keV and 2-10 keV bands assuming the best fit model of the sum of point sources (see text for details). Unabsorbed, k-corrected luminosities in erg s-1 are in the 2-10 keV band. The sources are also reported in the Appendix in RA order for completeness; however, in the Appendix the fluxes are all computed under a different spectral hypothesis (see text). These sources are identified by their number in the last column of Table A.1 for easy reference.

N.B.: Sources #4, #8, #18 and #27 in Gao et al. (2003) are not detected by us. Our sources N.18 and N.21 are not detected by Gao et al.
Luminosities in [ ] indicate sources that could be modulated by higher absorption because they appear to have a soft/hard count ratio different from the others.
a) Not used to compute the Luminosity Function.
b) Associated with G1; G2 is below our detection threshold.
