VPF in redshift space is shown for the theoretical framework (lines) and simulations (dots) given in the top panel, while the ratio between simulations and theoretical framework is shown in bottom panels for the Uchuu, P18, Low and VeryLow box catalogues with number density $\overline{n}=3\times {10}^{-3}{h}^3$Mpc⁻³. Shaded region in bottom panel indicates delimits the region between 0.9 and 1.10 for the ratio.
