real branch while the S$_{im}$ contribution is given by S$_{im}$ = S − S$_{r}$ . In order to get a better understanding of the role played by each contribution to the entropy, Fig. (8) shows the be- havior with density for a fixed temperature of s ∗ $_{im}$, s ∗ $_{r}$, s ∗ id and s ∗ $_{ex}$. It is immediately evident that s ∗ r shows a very similar density dependence to s ∗ $_{id}$, even though the numerical value of s ∗ r is significantly lower. Other than a small inflection at ρ ∗ ≈ 0 . 1, the contribution of the real INM modes to the entropy carries virtually no signature of the structural, entropy or
