Figure 10 shows the total structure factors S(k) for as-prepared versus annealed glassy NAGP with x = 0, 0.4 and 0.8. The red curves give the GEM data sets and the black or blue curves give the D4c data sets, where the latter correspond to the x = 0 glass annealed at T_{TT} = 876~K for either 0.25 or 0.5~h.
