Solid contours indicate log ₁₀(ℒ/ℒ_hom) for the AP Planck frequency maps as a function of central matter density parameter, , and the width of the void in redshift, z_L. The deepest voids have the smallest values of . Dotted contours are the 1, 2, and 3σ confidence levels from Zibin & Moss (2011), using the Union2 SN data. Void models which fit the SN data are ruled out at very high confidence by the kSZ data.
