Joint-fit eclipse depth as a function of aperture radius for different detrending methods. The FN-PCA detrending with a 5-pixel aperture is chosen for the fiducial result, as it minimizes the BIC, and the shaded region marks this result with error. The data used to create this figure are shown in Table 3. Our FN-PCA detrending is more stable under the choice of aperture size than the polynomial detrending, where the eclipse depth decreases linearly with aperture size.
