JWST spectra of VHS 1256 b (dark gray dots), overlaid by the Sonora Diamondback (Morley et al. 2024) best fit model spectra for each of the 15 independent spectral windows. Corresponding posteriors for effective temperature, T_eff, surface gravity, log g, metallicity, [M/H], cloud parameter, f_sed , and scaling factor, f , are presented in the five lower panels, where the parameter range of the grid itself is indicated by the colored area. The posterior values and corresponding errors when using the entire spectrum are shown by the gray line and shaded gray area, respectively. Dashed lines represent the corresponding averaged values from the machine learning retrievals with HST data (see Figs. 5 and 6).
