Caption: Figure 14.

The TRAPPIST-1 b and TRAPPIST-1 e transmission spectra, along with the resulting spectroscopic ratio, for the consistent light-curve fitting test. All reductions show close agreement, suggesting that the differences in spectra seen in Figure 3 are due to choices made during the light-curve fitting process rather than the generation of the light curves from the raw data.
