Notes. The value of ω given in the present table corresponds to that of the visual orbit of B around A (it thus differs by 180° from that of A around the centre of mass of the system, obtained for purely spectroscopic binaries). ϖdyn is the orbital parallax, which is obtained from the ratio a (′′)/ a (AU).
