Extended Data Fig. 5: Comparison of JWST instrumental modes across their overlapping wavelength regions.

Each panel shows the residual when comparing the spectroscopic transit depths as determined by binning before light curve fitting is performed versus those determined by directly binning the measured transmission spectrum at the native spectral resolution. Panels a–d indicate the residuals for each marked filter, where limb darkening parameters are fit for, and panels e–h indicate the residual for each marked filter, with limb darkening parameters fixed during the fit. The width of each shaded region corresponds to the 1σ uncertainty in the measured residual. Dashed lines indicate zero deviation.
