Overview plot of the temperature, emission contribution, and cloud properties of the “winning” SiO cloud model with amorphous spherical particles, two atmospheric columns, and evolutionary priors. Panel a: retrieved pressure-temperature profiles. The pRT retrieval profile is shown in magenta. The 1–3 σ posterior regions of the temperature are indicated by progressively lighter magenta tones, but are difficult to distinguish because of the narrow posteriors. We also overplot the log₁₀(g)-scaled P-T profiles of the grid models that are closest to the best-fit values obtained with species. Panel b: logarithmic emission contribution function of atmospheric Columns 1 and 2 as orange and purple contours. While nominally computed to sum to unity over all pressures at a given wavelength, the values have been scaled by the relative contribution of the two columns to the total atmospheric solution and multiplied by the wavelength-dependent flux. Panel c: size distribution of SiO cloud particles in Column 1 (shown in red), and Fe cloud particles in Column 1 and 2 (shown in blue and orange, respectively). For better comparability the distributions’ peak values have been normalized to the same y-axis values. The envelopes around the median distribution would correspond to the 1-σ uncertainty if the posterior variations around the median followed a Gauss distribution. Panel d: altitude-dependent cloud mass fraction of the SiO cloud (present in Column 1, shown in red) and of the Fe cloud (present in both Columns, shown in blue). The colored envelopes again represent the 1-σ uncertainty spread of the posterior distribution. The dashed lines correspond to the expected cloud deck position, obtained from intersecting the sampled P-T curves (see Panel a) with the saturation vapor pressure curves of SiO and Fe from Gail et al. (2013); Ackerman & Marley (2001). Panel e: SiO nucleation rate computed according to Gail et al. (2013).
