The cumulation of log B₁₀ as a function of increasing data. The plot shows only the 447 orbits used for the secondary eclipse modelling (see Sect. 5.2). The upper plot shows the trace for the maximum log B₁₀ case (identified as a slashed line in the lower plot), and the lower plot shows log B₁₀ mapped as a function of a sliding prior on the eclipse centre (as in Fig. 11) on the y-axis, with the amount of data (number of orbits included) increasing on the x-axis.
