Quality flag (Q): I
Comments:
The first 3D determination of the orbits in this triple system came from combined spectroscopic and interferometric techniques (Sana et al. 2013).
The multiplicity has been further investigated using long baseline interferometry and spectrocopy by Le Bouquin et al. (2017).
