Transmission spectrum of HD 209458 b with the best-fit model (gray line) and opacity contributions (colored) for the 1D atmospheric retrieval using petitRADTRANS. The green data points are the HST STIS+WFC3 measurements from D. K. Sing et al. (2016) while the purple ones are the two transits observed by JWST NIRCam using our uniform (limb-averaged) Eureka! reduction.
