Table 3: Individal measurements. Columns are (1) date of observation, JD₀ = $2\; 453\; 200.5$ ; (2) phase; (3, 4) u-v coordinate in meter; (5) squared visibility and error; (6) corresponding limb darkened disk diameter in mas; (7, 10) HD number of calibrators, prior and after the given data point respectivaly, 0 means that there was no calibrator; (8, 9, 11, 12) quantities for computing the correlation matrix (Perrin 2003): $\sigma _{V^2}$ are errors on the estimated visibility of the calibrators.
