Top: correlation result for our data set as a function of sini. The correlation remains flat along every inclination without any distinctive peak, the maximum value is reached at sini = 0.71. Bottom: goodness of fit, χ²-map, of the correlation models to the data. The horizontal and vertical axes refer to the fitting parameters sini and F_p/F_s respectively, at which the synthetic planetary spectrum was added in the correlation models creation, from which we calculated the minimum squares (). We plot χ² relative to the best fit () using the function exp(−αΔχ²). The gray scale denotes the goodness of fit, from black for the best fit (at ), to white for the poorest fit. The plotting parameter, α, just enables a good contrast in the plots (the same value was used for all plots). Additionally, we determined with bootstrap procedures the solid lines (bottom to top) that mark the (1, 2, 3 and 4-σ) levels of false-alarm probability. The white cross marks the best fit at sini = 0.84 and F_p/F_s = 3.6    ×    10^-3, situated below the 3-σ confidence level.
