Table 1:

Properties of the 3 massive UCDs detected in our survey, ordered by magnitude. Errors are given in parentheses. ``CCOS'' in the object identifier stands for Centaurus Compact Object Survey, see also Mieske et al. (2007). The last column gives a 2 $\sigma$ upper limit to the half-light radius in pc estimated from HST WFPC2 archival imaging.
