Notes. The orbital elements are the orbital period P, the eccentricity e, the argument of the periastron ω from the ascending node, the time of passage at periastron T0, the velocity of the centre-of-mass V0, the primary and secondary velocity amplitudes KA and KB, the projected primary semi-major axis on the plane of the sky aAsini and the primary to the secondary mass ratio MA/MB. σA(O−C) and σB(O−C) are the standard deviation of the residuals (observed − calculated) of components A and B. N is the number of avalaible CCFs on which two velocity components are identified. For the meaning of ΔVB see Eq. (2) of Pourbaix & Boffin (2016).
