Overall density distribution, moment free

Nevertheless, we see already from Fig. 9 that, for the current example, the robustness of the results to the addition of extra moment densities provides a reasonable qualitative check of the accuracy of the coexistence curves. To study the convergence of the moment free energy results to the exact ones more quantitatively, especially in cases where the latter are not available for comparison, we need a measure of the deviation between ptot((r) and p (dimensionless quantity that does not scale with die overall density of the parent, we consider the normalized distributions nMt(a) — Ptot(ff) / Ptot and (a) = /c/°) (cr) / pW and define as our measure of deviation...
