Photometry profile for the rescaled stacking of half the Sutter et al. lrgdim subsample (146 voids out of 291), chosen so that the amplitude at 0.56 times the voids radii is the strongest (see text for details). Left: the significance is estimated with stacks of 146 random positions. Right: the significance accounts for the selection effect. The difference between the two significances is obvious and very pronounced.
