Top Panel: comparison of the values of the AP parameter ε with its error σ_ε (error bars), obtained with the fitting procedure described in Section 4, for the analysis with tracers and voids in redshift-space (orange dots) and the analysis with tracers and voids in reconstructed space (blue triangles). Each dot represents the ε value as a function of the minimum radius R_min for the voids in that specific subsample, expressed in mean tracer separation (mps) units, used for computing VGCF. Bottom Panel: improvement factor I, i.e., the ratio between σ_ε estimated in redshift space and reconstructed space.
