Same power spectra as in Fig. 4 but with scaling tested a little differently. The power spectra and wavenumbers at the eight output times are scaled so that they would all lie along a single curve if the scaling were correct. Again, the standard self‐similar scaling shown in the left panel works better than the alternate velocity scaling shown in the right panel. The lower dashed line shows the linear spectrum. The upper dashed line has arbitrary amplitude, but its slope is predicted by the stable clustering hypothesis. The N‐body spectra asymptote to this slope at high k.
