Caption: Figure 2.
White light curves of HD 191939 b’s primary transits observed with HST/WFC3 and reduced and modeled with PACMAN. The systematics-corrected light curve only shows the exposures that were analyzed in the light-curve fit. A reference line at zero was added in the residuals panel to guide the eye.
