neighbors is essentially flat. This adds a (negative) constant to the free energy, so the phase behavior [@widom] and dynamics of the system are still controlled by repulsion (or, equivalently, entropy).

Note that the shape of the DSF of sample C at $qR = 1.50$ is similar to that shown in curve 2, Fig. 11 of [@glassMCT]. This DSF was calculated at $qR = 2.1$ for a sample in the re-entrant portion of the state diagram in a system that [*just*]{} shows a glass-glass transition and an A3 point. Recent calculations for colloid-polymer mixtures [@gelMCTHiPhi] suggests that our system, with $\xi
\approx 0.09$, should show exactly these features.

The DSFs of samples F–H are, once more, non-ergodic in our time window: they do not decay completely even after $10^4$ seconds. Simple extrapolation indicates that it would take these DSFs at least $10^6$ seconds to reach zero. The DSFs of samples G and H show points of inflection; that for sample H is clearer and occurs at $f = 0.995$ — a very high value compared to the plateaus in hard-sphere glasses. These high points of inflection can be associated with dynamics originating from particles rattling in very narrow attractive potential
