Notes. Summary of modeling results for Gl 570D and HD 3651B using petitCODE clear models and comparison to atmospheric retrieval results by Line et al. (2015).
Difference of best fit model to middle of metallicity range of host star. Uncertainty includes the width of host star metallicity range in all cases, as well as uncertainty for brown dwarf metallicity in the petitCODE case. Host star metallicities used here: Gl 570D: −0.22–0.12 or − 0.05 ± 0.17 (Line et al. 2015); HD 3651B: 0.11–0.25 or 0.18 ± 0.07 (Ramírez et al. 2013).
