Fit planetary transit depths from JWST white-light curves using different limb-darkening assumptions as a function of stellar effective temperature. The measurements have been slightly offset in temperature for clarity. The depths are relative to the Bayesian Model Average (BMA) transit depth, using the BPICS to measure the model probabilities. The 1σ uncertainties are shown as well as the transmission spectral amplitude of one pressure scale height, H.
