Notes. Reported numbers for K1 and K2 bands are mean values and their random uncertainties (standard error of the mean). When a second uncertainty is reported, it refers to the systematic uncertainty of the pixel scale and true north correction, respectively (see Sect. 4.2.1). The values of the separation in AU were obtained using the new parallax measurement from the Gaia mission (Gaia Collaboration 2016).
