Notes. The parameters i (range of value), log g = 3.011, and T = 24 985 K were fixed, while m, Ω, Prot free. Otherwise, χVIS2 and χSPE2 were computed as in Table 3. The best-fit model based on interferometry (i = 60 deg) is shown in Fig. 6, while the best one based on spectroscopy (i = 20 deg) is in Fig. 7.
