  \caption{The widest known binary systems in \sco{}. For each of these binary systems we list the angular separation, the \hipp{} parallax, an estimate for the semi-major axis $a_{\rm est} \equiv D\tan \rho$, the subgroup, and the spectral type of the primary. The last column lists the reference. Note that this list must be incomplete, as very wide binaries are difficult to detect. Furthermore, several of these binaries may be optical due to confusion with background stars, i.e., not physically bound.
