  \caption{We have obtained follow-up multi-color observations with NACO for 22~targets in the Sco~OB2 association. We include in our analysis 9~targets with multi-color observations in the ADONIS sample. All targets listed above are known to have secondaries in the ADONIS survey.  The table lists for each star the parallax and error \cite[taken from][]{debruijne1999}, the $K_{\rm S}$ magnitude, and the spectral type of the primary star. The $K_{\rm S}$ magnitudes are those derived in this paper for the 22~stars observed with NACO, and are taken from \cite{kouwenhoven2005} for the other nine stars. The last column shows the subgroup membership of each star (US~= Upper Scorpius; UCL~= Upper Centaurus Lupus; LCC~= Lower Centaurus Crux), taken from
    \cite{dezeeuw1999}. \label{table: sample}}
