Theoretical redshift-space CCF calculated for a range of fiducial cosmologies. The left-hand side shows how the theory responds to changes in the AP distortion parameter ε when the real-space CCF ξ^rr comes from the data, while the right-hand side shows the same for the case when ξ^rr is given as a template from simulations. From top to bottom, the three large panels show the monopole, quadrupole, and hexadecapole, while the residuals show the difference between the multipoles at a given ε and the multipoles when ε = 1.
