Results of high-resolution retrieval. Corner plot: posterior distributions and correlations between the atmospheric parameters. The dashed vertical lines in the posterior distributions denote the median and 1σ intervals for the bounded parameters. For parameters with upper or lower limits, we report the 2σ intervals. Panel a: examples of the T-p profiles sampled by the MCMC analysis, showing that the bottom of the thermal inversion is poorly constrained. Panel b: median temperature curve with 95 percentiles derived from 3000 random posterior draws.
