Figure 4. Factorization of energy density profiles.

(a) W_τ(x)/W_τ=1(x) for the three ensembles of samples of Fig. 1 (blue and red curves) and a sample with L/ξ=0.025 (green curve). The black dashed curves are given by equation (5) with h(x/L) shown in b. Curves of simulations of W_τ(x)/W_τ=1(x) for the same values of τ in different samples and for S_τ(x) given by equation (5) overlap. (b) h(x/L) determined from equation (5).
