Fig. 2 (caption). The 3-D galaxy distribution in the foreground of the CMB Cold Spot (black points) compared to the galaxy distribution in an area with no background Cold Spot (red points). The number and size of low galaxy density regions in both areas are similar, making it hard to explain the existence of the CMB Cold Spot by the presence of voids.
