Top panel: Two-point correlation function obtained using the LS estimator for the total sample, z ∈ [1.2, 2.8]. Red point represents the correlation function with its error bars. Bottom panel: The dashed red curve indicates the best linear fit in logarithm scale. In the linear regime, the correlation function can be parametrized as ξ(s) = (s/s₀)^−γ with γ = 1.21 ± 0.03 and s₀ = 12.25 ± 1.30.
