Map of TiO S/N detection significance when excluding different orbital phase ranges around the secondary eclipse (measured at K_p = 248.0 km s⁻¹ and Δv = 0.0 km s⁻¹). The values on the x- and y-axis show the boundaries of the excluded phase intervals. The signal of TiO peaks when the orbital phase interval between ~ 0.37 and ~ 0.60 is excluded. The corresponding phase values are indicated with a red star (). We checked the exclusion of all possible orbital phase intervals. Phase ranges that are entirely inside eclipse were not considered (between roughly 0.45 and 0.55).
