Table 2: 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 (taken from de Bruijne 1999), the magnitude, and the spectral type of the primary star. The magnitudes are those derived in this paper for the 22 stars observed with NACO, and are taken from Kouwenhoven et al. (2005) 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 de Zeeuw et al. (1999).
