Top row: map of the linear intensity in the TiO band transition A³Φ − X³Δ(γ) of Fig. 10. The range is [0; 3.5 × 10⁵] for the gray simulation st35gm03n07 of Table 1 and [0; 4.5 × 10⁵] erg cm^-2 s^-1 Å^-1 for the non-gray simulation st35gm03n13. Bottom row: visibility curves obtained from the maps above. The visibilities were computed for 36 different azimuth angles 5° apart. Bottom right panel: visibility fluctuations with respect to the average value for the gray (solid line) and non-gray (dashed line).
