\tablefoot{The apparent optical magnitude from \cite{Veron2006} is denoted $V$, the  redshift $z$, and the type of the object is ``BL'' for BL~Lac objects and ``QUA'' for quasars. The right ascension $\alpha$ and declination $\delta$ are extracted from the catalog specified in the third column. The mean correlated flux densities are given in mJy, the derived $S/X$~spectral index is denoted $\alpha_{SX}$, and the name of the experiment is given in the last column (``A'' for EC025A and ``B'' for EC025B).\\
IERS name of gravitational lenses is marked with an asterisk. These sources will be omitted from subsequent steps of the project.\\
The catalogs from which the coordinates were extracted are: CLASS (\citealp{Myers2003}; position accuracy $\sim$35~mas), CRATES (\citealp{Healey2007}; position accuracy ranging from $\sim$50~mas to $1^{\prime\prime}$), FIRST (\citealp{Becker1995}; position accuracy ranging from $\sim$50~mas to $1^{\prime\prime}$), NVSS (\citealp{Condon1998}; position accuracy $\sim$$1^{\prime\prime}$), and AHA (Andrei, A.~H. 2007, private communication of improved positions for QSOs as extracted from the input catalog for Gaia; position accuracy better than $1^{\prime\prime}$). For the last catalog, the name of the source written in the table is extracted from \cite{Veron2006}.}
