Notes. φ1 (φ2) denotes the orbital phase of orbit 1 (2), B the mean length of the projected baseline, θ the position angle of the projected baseline. The calibrator stars are identified as follows: 1 – HD 21686, 2 – HD 18604, and 3 – HD 26793. Ephemeris used to compute the orbital phases: 1 – Tmin,1(RJD) = 7.1467 × E + 56 224.7246, 2 – Tp,2(RJD) = 145.17 × E + 55 609.05, where E is the epoch, 
the epoch of the primary minimum of orbit 1, Tp,2 the epoch of the periastron passage of orbit 2.
