Structure function ﹩\mathrm{\ln}_{2}[ S^{2n}_{j}/ ( S^{2}_{j}) ] ﹩ vs. j for HS 1700+6416 of real data (circles) and hydrodynamic simulation with 12 Mpc box (triangles) and 6 Mpc box (squares). The physical scale for j is ﹩\Delta v=2^{13-j}\times 4﹩ km s⁻¹. For clarity, the results of the two simulation samples are shifted slightly.
