a Object classified as candidate interloper ( $\mathcal{P}$ < 0.1% within the uncertainties, see Fig. 3); b resolved as a visual multiple system and discarded from the list of outlier candidates.
Note. All the objects come from Preibisch et al. (2002) sample. r is the distance between the object and its closest UCAC2 counterpart. The membership probability is indicated in the last column.
