Comparison between Pytmosph3R, batman (T₀ = 0), and Juliet (values retrieved in Fig.C.1). For each subfigure: Left: Light curves generated by Pytmosph3R (dashed line) compared to Juliet (solid line). Right: Residuals of batman (blue) and Juliet (orange) compared to Pytmosph3R. The residual of Juliet is lower on average than that of batman, mainly because of the shift in T₀. Using N_egress = 30 and N_ϕ = 100 leads to a statistical overrepresentation of the egress or ingress in the retrieval, which can be corrected using an interpolation over N_ϕ = 300 phases (see Fig. C.2).
