Table 3
Summary table for the six atmospheric retrievals performed in this work (two on real JWST data and four on simulated observations).
| Planet | Timescales | Speedup | log-Bayesian evidence | log-Bayes factor | ||
|---|---|---|---|---|---|---|
| Uniform prior | Informative prior | Uniform prior | Informative Prior | |||
| WASP-39b | 498 h | 64 h | 7.8 | 668.04 ± 0.14 | 669.20 ± 0.14 | −1.16 |
| WASP-17b | 86 h | 27 h | 3.2 | 413.52 ± 0.10 | 408.64 ± 0.11 | 4.87 |
| Simulated 1 | 44 h | 36 h | 1.2 | 2185.67 ± 0.11 | 2185.21 ± 0.11 | 0.46 |
| Simulated 2 | 71 h | 65 h | 1.1 | 2175.64 ± 0.11 | 2174.42 ± 0.11 | 1.22 |
| Simulated 3 | 33 h | 27 h | 1.2 | 2189.13 ± 0.10 | 2191.779 ± 0.09 | −2.649 |
| Simulated 4 | 23 h | 20 h | 1.1 | 2183.214 ± 0.08 | 2181.244 ± 0.09 | 1.97 |
Notes. The first three columns show the computational timescales for the retrievals with uniform and informative priors, along with the corresponding speedup. The last two columns show the log-Bayesian evidences for the same retrievals and the corresponding log-Bayes factor (computed following Kass & Raftery (1995); Trotta (2007) as the difference between evidences with uniform and informative priors).
