The high-resolution density fields of the model M256.256 are shown in the left column, at the k = 140 coordinate. The second, third, and fourth columns show the wavelet w5, w4, and w3 decompositions at the same k, respectively. The upper row gives data for the present epoch, z = 0, the second row for the redshift z = 1, the third row for the redshift z = 5, and the last row for the redshift z = 10. Densities are expressed on a linear scale. In wavelet panels, green and red colours show the positive regions of wavelets, and the blue colour shows negative (under-density) wavelet regions. Colour codes are plotted at the bottom of the figure for wavelet w3 at epoch z = 10.
