Summarized results of the retrievals on the WASP-107 b HST and JWST data. The top left panel shows the observed spectra corrected for offsets for the FRECKLL retrievals (data points), the best fits of the free and FRECKLL retrievals (solid lines), and the contributions from the FRECKLL HST+NIRCam+MIRI retrieval (shaded areas). The top right panel shows the retrieved thermal structures including 1 σ and 3 σ confidence regions (shaded areas), as well as the cloud condensation curves from Wetzel et al. (2013); Gao et al. (2021); Grant et al. (2023). The middle row shows the chemistry and aerosol structure (SiO₂, MgSiO₃, and Mg₂SiO₄) for the four retrievals. The bottom row shows the retrieved probability density. The metallicity (Z) is directly retrieved from the FRECKLL retrievals but estimated from the O/H (normalized by WASP-107 value) in the free retrievals. Overall, the atmosphere of WASP-107 b is consistent with high-altitude Si-clouds, but the exact solution somewhat depends on the considered data (NIRSpec or NIRCam) and model assumptions. Figure C.4 shows the incompatibility of the NIRSpec and NIRCam spectra, leading to slightly different solutions.
