Upper panel: binned transit for the merged, reconstructed LCs (gray), their U-bottomed trapezoid fits (black, binned, and averaged in the same way as the data). Lower panel: gray points as above, black points are the weighted averages of the gray points. The yellow line shows the best-fitting flat-bottomed trapezoid for the secondary eclipse. The stroboscopic effect (exhibiting as small gaps) is not visible in the lower panel, because of the extended horizontal scale.
