Quadrupole moments of the real and redshift-space CCFs for all void finders, with voids found in redshift space. Left: Quadrupoles of the real-space CCF in the true cosmology (red) and a fiducial cosmology with ε = 1.053 and q = 1 (yellow and green). The yellow line is the assumed case where voids move under AP distortion in the same way as halos, while the green line is the more realistic case where voids are found in the distorted halo field. Right: Quadrupoles of the redshift-space CCF in a fiducial cosmology which differs from the truth (ε = 1.053 and q = 1). In red we plot the theory prediction, calculated using a template ξ^rr.
