AP filter outputs for ISW maps derived from the zHORIZON simulations. The black, green and blue symbols refer to density excursions in the projected density maps having twice, same and half the angular number density as voids and superclusters from G08. Circles correspond to underdensities and squares to overdensities. These excursions were identified in projected density maps smoothed down to pixels of ∼2 ° on a side (N_side = 32).
