Comparison of nested POSEIDON Model B retrievals with and without H− and AlO, zooming on the 0.2 to 1.05 µm region. We display median retrieved spectra (solid lines) and 1σ confidence regions (shaded regions). Model B with both H− and AlO (blue) is the best fit model, but only due to imparting fine structure to fit the STIS slope. Future observations of the 0.2-0.8 µm region will provide more reliable inferences of metal species. -- astro-ph.EP
