Appendix A: X-ray source catalog in the ``Daddi field'' and X-ray spectra of EROs

Table A.1:   X-ray properties of the sources detected by Chandra in the ``Daddi field''.

\end{figure} Figure A.1:

Chandra spectra (folded with the response of the ACIS-I instrument) of the three X-ray EROs with most counts in the 0.5-8 keV band. While for the spectrum of ERO #2073 a single power law model was assumed, for the remaining two objects absorption at the source rest-frame (using the spectroscopic redshift for ERO #2160 and the photometric redshift for ERO #3629; see Table 1) was included in the spectral fitting, as described in Sect. 4.2. The three bottom panels illustrate the data/model ratio in units of $\sigma $.

Rest-frame X-ray spectrum of the 11 EROs that are individually detected in the Chandra observations. The underlying model consists of an absorbed power law.
