Performance comparison between different retrieval studies. The error bars correspond to the 68% confidence intervals of the retrieved posterior distributions. The emitted light study from this work for (R = 50, S/N = 10 (green downward triangle) and R = 35, S/N = 15 (orange upward triangle), 3–20 μm in the optimized case); the reflected light study by Feng et al. (2018) (R = 70, S/N=10 (blue dot), R = 70, S/N = 15 (red square), 0.4–1.0 μm).
