\begin{table}%T1
\caption{List of sources that are detected in the area covered by the
Cartwheel system and displayed in 
Fig.~\ref{chhard}. 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~\ref{wavsrc} for easy reference.}

N.B.: Sources \#4, \#8, \#18 and \#27 in Gao et~al. (\cite{Gao03}) 
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.
