Legenda for the FLAG column: $0$~-- counterpart published in S04; $1$~-- counterpart different from the one published in S04; $2$~-- new published counterparts (sources detected only in A03). Notes on single sources: $^k$: source published in Koekemoer et~al. (\cite{Koek04}); $^m$: source published in Mainieri et~al. (\cite{Main05}); $^r$: source published in Rodighiero et~al. (\cite{Rodi07}); $^{aa}$: source published by \mbox{Alonso-Herrero} et~al.

The redshift column report the photometric or spectroscopic redshift. When a spectroscopic redshift is present, the relative source catalog is reported, as follow: (1)~CXO-CDFS (S04); (2)~K20 (Mignoli et~al. \cite{Mign05}); (3)~GOODS-FORS2 (various releases); (4)~GOODS-VIMOS (Popesso et~al. 2008); (5)~COMBO-17 (Wolf et~al. 2003); (6)~GMASS; (7)~others: VVDS, Daddi, TrzK, LCIRS ast0612152 Otherwise, the redshift is from SED fitting. (CCC): photometric redshift soultion preferred to the low-quality spectroscopic redshift available; $^{v}$:~this object has a different redshift solution from the VIMOS observation, $z=0.798$ (Popesso et~al. 2008). \end{table}
