Constraints on ε when assuming different fiducial flat ΛCDM cosmologies (top part of Table 1). Yellow points are for the test case where both halos and voids were moved by hand, while the red points are for a more realistic case, where voids were found in the distorted halo field. The x-axis shows the ε corresponding to the fiducial cosmology, while the y-axis is the best fit. The diagonal black line represents the point where the best-fit ε matches the fiducial one.
