Effect of the assumed average color of the grand-averaged light curve (Fig. 10) on the transit anomaly. The continuous curves show the best fitting models from B (the deepest curve) through V, R to I (the shallowest curve). The dots represent the (shifted) residuals remaining after subtracting the model light curves corresponding to B and I (upper and lower sets of points, respectively). The “kinks” in the I residuals in the ingress/egress parts suggest that shorter wavebands give a better representation of the mixture of colors the grand-averaged light curve is assembled from.
