The evolution of the local density and wavelets of the models L100.100 (left panels) and L100.016 (right panels) in beams along the i-coordinate at j = 220, k = 51. The same k-coordinate was used in plotting the density field in Fig. 3. Data are shown for epochs z = 0,   2,   5. To see better details only the region 144 ≤ i ≤ 400 of length 50 h^-1Mpc is shown. The characteristic scale of the wavelet w5 is 12.5 h^-1Mpc. Wavelets are divided by the factor f ∝ (1 + z)^-1.
