Notes. This table only reports the characteristics of the Kelp,refl component. The characteristics of the cosine component are reported in Table 1. Several marginalised posteriors are not Gaussian and mostly provide upper/lower limits. In these cases, we provide in this table the 68th percentile as upper limit or the 32nd percentile as lower limit, but we also provide the median and the border of the 68% confidence interval, as described in Sect. 4.2, as the combination of the two allows us to better describe the posterior. ^(a)x₁ and x₂ are defined such that -90º and 90º correspond to the western and eastern terminators respectively.
