The top and middle rows show the distributions of the local estimates of the mixed third-order structure functions, Y^out(ℓ_⊥) and Yⁱⁿ(ℓ_⊥), respectively, as a function of the perpendicular lag ℓ_⊥. The color scale indicates the number of samples contributing to each bin, while the red curves denote the corresponding mean values. The bottom row displays the average quantity Y = (Y^out + Yⁱⁿ)/2. The quantities plotted here are calculated using the two intervals shown in Figure 1.
