Mean CMB temperature within 0.5R_void of each individual void for voids within the largest quartile. Voids are taken from the combined Sparkling sample, where only voids appearing in > 50% of the random realizations are included, corresponding to the voids that have the largest weights in the void weight maps of Figure 1. The fact that the void position and radius differ slightly for different realizations is reflected in the varying temperature within one single void for some of the voids.
