Top: Isotropic two-point correlation function measured directly (red) and derived from the power spectrum (blue). Bottom: Log–log plot of the direct estimate of ξ(r) = ⟨δ(x) δ(x + r)⟩. The slope ≃ − 1.4 over the range [45, 250] h−1 Mpc implies a correlation dimension D2 ≃ 1.6. The dashed line marks the scale below which smoothing becomes significant.
