Analysis (i): lowest value of reduced χ² () for each value of R_eq∕R_p (left panel) and stellar mass (middle panel) from the HDUST fit to the VEGA V² data (642.5 nm band). Local regression fits to , as a function of the parameter values, are shown in red line. In the right panel, the predicted visibility from our best-fit HDUST model (red points; Table 5) is compared to the VEGA V² measurements in the continuum band (black points). The predicted visibility from the HDUST model with the highest mass in the BeAtlas grid (14.6 M_⊙, highest in the middle panel) is shown in blue points.
