Comparison among true values of J_{i, i + 1} (circle symbol), reconstructed J′i,i+1 (cross symbol), and predicted J′i,i+1 (triangle symbol) from perturbation analysis under the linear approximation when (a) N = 50 and J_{i, i + 1} = 1, (b) N = 100 and J_{i, i + 1} = 1, (c) N = 50 and random J_{i, i + 1} ∈ [0.9, 1.1], and (d) N = 100 and random J_{i, i + 1} ∈ [0.9, 1.1]. The reconstruction starts with a pair of C_{1, n} truncated.
