Evolution of the different mass components of the haloes in the sample and their fraction of ordered rotation κ from their infall redshift z_inf to their z = 0 values. Contour levels show the 75, 50, 25, and 5% of the maximum counts of the distributions. The horizontal lines at 0 and −1 correspond to no change and maximum mass loss, respectively. The position in the plane of objects beyond the 5% contour are shown as square markers.
