Local cosmography of CF4 (left) and CF4++ (right) centred on SGZ = −3.9 h⁻¹ Mpc, averaged over a total width of 24.3 h⁻¹ Mpc. The first row shows the mean of the HMC realization density contrast (δ) and is overplotted by the mean radial velocity field. The second and third row respectively show the standard deviation of the density contrast fields and the radial velocity fields. The grey contours overplotted on these slices are the equivalent contours lines, where δ = 0.
