χ² maps between our models and the CHEOPS data point for chemical equilibrium models (bottom) and models where TiO and VO have rained out of the atmosphere (top). The contour shows the region that agrees with the data within 3 σ. The rainout of TiO and VO allows an easier condensation of the silicate clouds, and thus a high albedo at lower metallicities than for the case in chemical equilibrium.
