Similar to Figure 6, but contains the spectra for T-1 e, f, g, and h. The left column shows transmission spectra for T-1 e, and is laid out the same as the left column of Figure 6; spectra are colored by their fit to the recent T-1 e transmission data (N. Espinoza et al. 2025; A. Glidden et al. 2025). T-1 e has no stable H₂O-dominated or mixed H₂O–O₂ atmospheres. The middle column shows transmission spectra for T-1 g, the top two panels of the right column show transmission spectra for T-1 f, and the bottom panel of the right column shows transmission spectra for T-1 h. T-1 f, g, and h are too cold to sustain any stable atmospheres supported by H₂O outgassing alone. T-1 g has all H₂O–CO₂ outgassed archetypes, but T-1 f is missing mixed O₂–H₂O–CO₂ atmospheres and T-1 h only has stable CO₂–CO atmospheres.
