Notes. We prefer the solution from the three-step method (bold). The anomalistic period Panom, 1 and the pericentre rate 
were fixed. Free parameters were the time of periastron passage T0, eccentricity e1, argument of periastron ω1, semi-amplitude of the primary K1, mass ratio q1, standard deviations of the intensity factors for the primary, secondary, and tertiary, σs1, σs2, σs3, respectively. The dependent parameter is the semi-amplitude of the secondary K2. The models are quantified by pseudo-χ2 in Fourier space.
