Notes. T0 denotes the time of periastron passage; (m1 + m2), the mass of Aa1+Aa2 (the primary in this model); m3, the mass of the Ab component (the secondary in this model); P2, the orbital period of Aa and Ab; e2, the eccentricity; i2, the inclination; Ω2, the longitude of the ascending node; ϖ2, the longitude of periastron; λ2, the true longitude; γ1, the systemic velocity attributed to Aa1+Aa2; and d, distance. f indicates the respective parameter was fixed.
