Notes. We compare the ANDES golden sample with the addition of Barnard b with a potential Earth-like and ocean planet around Alpha Cen A. We compare the contrast estimates from Pallé et al. (2025) with our updated calculations using the 3D Cloud Generator (3D CG) in both reflected and polarized light. Additionally, we present contrast values obtained for an ocean planet with a coarser horizontal grid resolution (zoom-out x100) for comparison.
