Void wavelet temperatures of voids with R_void within the largest quartile in 100 simulated CMB maps without (upper panel) and with (lower panel) the quadrupole removed. Black histograms show the void temperatures of the 100 simulations (of 10 000) with the coldest mean CMB temperature around galaxies and red histograms show the 100 simulations with the hottest temperature around galaxies. Blue line show the void temperature in Planck data. The histogram is shown with very small bins such that individual simulations are visible.
