Caption: Figure 1. Comparison between the new and the previous orbit for each system

The complete figure set (22 images) is available in the online journal.

New and previous apparent orbits for HU 29. The graphical representation of the orbits have been included as a figure set, accesible in the digital version of this article. For all the Figures and following ORB6 standards, the micrometric observations are plotted as green crosses, Hipparcos as H, the speckle observations are identified by blue circles, and the latest ones obtained by SOAR are designated with the violet + symbol. All of these symbols are united by their respective color line to the new orbit, joining the real observation with its expected position according to the time of observation. The previous apparent orbit is represented by a dashed black line and our new apparent orbit by a solid line. The line of nodes is traced by a solid straight line upon which the position of the primary star can be seen as a large cross. In the right corner we indicate the orientation of the axes, and the direction of orbital motion.
