Figure 1 shows the total structure factors F(k) for as-prepared glassy (a) As_{0.30}Se_{0.70}, (b) As_{0.35}Se_{0.65} and (c) As_{0.40}Se_{0.60}. The points with vertical error bars show the measured functions and the solid curves show spline fits. The error bars are smaller than the line thickness at most k values.
