Quadrupole of the VGCF computed with reconstructed data, for different choices of the fixed smoothing scale R_s used in the reconstruction procedure. Error bars are computed as the diagonal of the covariance matrix. The choice R_s = 5.0 h⁻¹Mpc results in an isotropic correlation function, corresponding in a measured quadrupole matching with the dashed black line, which is the expected zero quadrupole ξ₂^th = 0. Residual anisotropies are seen for other values of R_s. The quadrupole moment, and consequently the effect of R_s, is accentuated near the edge of the void due to the presence of nonlinearities caused by a higher density contrast.
