Geometrical parameters of WASP-3b estimated from individual data (sub-)sets (Table 2) plotted as black labeled circles in their two-dimensional parameter space to highlight the sizeable correlation between Σ_r, k_r, and i. The blue dashed line in each plot is a weighted linear fit of all points; the blue triangles and the associated error ellipse correspond to the weighted mean  ± 1σ computed on the marginal distribution of Σ_r, k_r, and i (last but one row of Table 2). The red continuous line and squares are computed in the same way as the blue ones, but after removing the outlier labeled “3” from the set (T1,T3; last row of Table 2).
