Posterior distributions for the secondary-eclipse retrieval of WASP-43b. The solar-metallicity and high-metallicity peaks described in the text are shown in the left and right column respectively. In each column, the upper panel shows the posterior for the metallicity [M/H], where the vertical, magenta line indicates the median of the distribution and the blue lines the corresponding 1-σ intervals. The lower panel depicts the retrieved temperature-pressure profile. The thick, red line is the median temperature profile, while the shaded red area is the 1-σ interval of the temperature distribution.
