Reconstructed correlation kernels for the different octants. We note that the logarithmic dust extinction in our model is the result of an a-priori normal distributed field that is folded with these kernels, dependent on the octant. The octants are arranged such that octant i = 4b₂ + 2b₁ + b₀ (for b_i ∈ {0, 1}) extends in positive x-direction if and only if b₀ = 0, in positive y-direction if and only if b₁ = 0 and in positive z-direction if and only if b₂ = 0. We note that all kernels fall to about 10% in the first 2 pc.
