\caption{Characteristics of sources~1, 2, 3 and~4 detected with the
10--7~combination scales. $\alpha$ and~$\delta$ are
the J2000 central coordinates of the sources. Area is the (square) area
used to compute the magnitudes and is given in~arcmin$^2$. The Gregg \& West (\cite{Gre98}, GW98) values are also reported for source~3.}\label{tab:col}
