Left: Tomographic cross-correlation signals for the voids identified in the full-sky DESI Legacy Survey and the corresponding calibrated Buzzard mock realizations. The measurements are provided for the full void samples and the three different λ_v bins, analyzed in four equispaced redshift bins with Δz = 0.15. Right: Summary of A_κ values for the various measurements (see Table 4). The blue vertical band indicates the 1σ confidence intervals for the full void samples from Fig. 12.
