Table A.1: Results from our multi-color binarity study among 22 Sco OB2 member stars observed with NACO ( top part of the table) and the subset of 9 members with multi-color observations in in the ADONIS survey ( bottom part of the table). The columns show the Hipparcos number (for the targets) and the secondary designation, the J, H, and $K_{\rm S}$ magnitudes, the angular separation, and the position angle (measured from North to East). Lower limits to the magnitudes are given if an object is not detected in the NACO survey, unless the ADONIS measurement was available (marked with a $\star $). Entries marked with $\star \star $ have no available measurement, e.g., because the object is not in the field of view for that filter. For each primary and companion star we list the absolute $JHK_{\rm S}$ magnitudes and the mass in Cols. 7-10. We additionally provide absolute magnitudes and a mass estimate for the candidate companions, under the assumption that these are indeed companions. We stress that a significant number of the candidate companions may actually be background stars. The 11th column lists the status of the object (p = primary, c = confirmed companion star, $\rm nc = new$ confirmed companion star, ? = candidate companion star; b = background star). The last column provides additional remarks. A remark "J'', "H'', or "K'' means that the secondary flux in this filter was obtained from the image obtained without the NDF, using the PSF from the corresponding image that was obtained with NDF (see Sect. 2.4). If the secondary status was obtained without color information, an exclamation mark is placed in the last column. The results for the 9 targets with multi-color information in the ADONIS survey are marked with "ADO''.
