Top panel: comparison of different ToV light curves. The black curve is the light curve combining the RHD simulation of the Sun (Figs. 5 and 6). The red and light blue curves represent the limb-darkening Magic et al. (2015) and Claret (2000), respectively. In the end, the purple curve represents the limb-darkening carried out using Claret’s law for the RHD ⟨ 3D ⟩ profile of Fig. 2 (green curve). In all the cases, a constant value is used for Venus intensity. Bottom panel: difference between the above curves with respect to the transit curve of the RHD simulation of Fig. 6.
