“…S(k, t, ǫ = 0, L) is plotted against q for the pure case. Different curves correspond to exponentially increasing times (t = 2,3,5,7,11,18, 29, 46, 73, 118, 189, 304, 490, 789, 1269, 2044, 3291, 5299, 8532, 13739, 22123, 35623, 57362, 92368, 148736, 239503, 385663, 621017, 10 6 from bottom to top)…”
