\begin{table}%T3
\caption{\label{oldx}X-ray sources previously detected in the field. 
The number in the first column refers to our internal numbering 
scheme (see Table~\ref{crate}).
Identifications with the~2RXP and 1WGA~catalogs
have only an indicative value. When there were two entries 
with the same name in the 1WGA~catalog, we kept only the 
source detected with the smallest off-axis angle, as
recommended by the WGA~team.
The second part of the Table deals with the diffuse extended
emissions. Several spurious X-ray sources were
detected in the~2RXP and 1WGA~catalogs at their position,
and we will not list them here. }
