Aurora and POSEIDON retrieval code comparison. Top: NIRSpec/G395H transmission spectrum from the transitspectroscopy reduction, with the two models varying retrieval codes overplotted. Bottom: Retrieval posterior distributions with their median values (solid lines) and their ±1σ confidence intervals (dashed lines). The POSEIDON (blue) and Aurora (gray) results are shown for the statistically preferred atmosphere + spots model (see Table 3 for full retrieval results).
