Notes. Column 2 lists the configuration used as a triple of stations (e.g. “AC-AE-W7”, using astrometric stations centre and east, as well as imaging station W7) if data from all three involved baselines were recorded, including the corresponding closure phase. When a single baseline is listed, only squared visibility data were recorded but no closure phases on that baseline. φ1 (φ2) refers to mean orbital phase of orbit 1 (2) at the given RJD. Calibrator numbers correspond to the numbering in Table C.4. 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, Tmin,1 the epoch of the primary minimum of orbit 1, Tp,2 the epoch of the periastron passage of orbit 2.
