Retrieval analysis joint with the transit depths presented in Yan et al. (2020) (LBT MODS) and Wong et al. (2020) (HST STIS G750; HST WFC3 G141; Spitzer IRAC). Upper panel: raw transmission spectra of the six data sets. Lower panel: shows the joint fit results with the effects of stellar contamination corrected for each data set. The green solid line is the median model with a resolution of λ∕Δλ = 200. The shaded areas indicate 68 and 95% credible intervals. The white dots are best-fit values calculated at the same wavelength bins as the corresponding data points. In the range of 0.5–1.0 μm, only the best-fit points corresponding to OSIRIS wavebands are displayed for clarity.
