\(\rho ^{\mathrm{s}}\bar v\) either side of an intensity step for various sample densities and speed ratios. The main plot shows \(\rho ^{\mathrm{s}}\bar v\) for the first tile on the slow (–) side vs. the same quantity for the first tile on the fast (+) side for several independent datasets. For both low density (filled symbols) as well as higher-density datasets (open symbols) Eq. (6) holds. This is also demonstrated in the inset, which shows (\(\rho _ - ^{\mathrm{s}}\bar v_ -\)/(\(\rho _ + ^{\mathrm{s}}\bar v_ +\)) vs. \(\bar v_ -\)/\(\bar v_ +\) for the same datasets. Error bars show s.d.
