In the original article (Ref. 1), the first line of the caption for Figure 4 contained errors that could cause the reader to misinterpret the data. The corrected first line of the caption is as follows: “The scaled chain relaxation time for N = 1000, P/σm = 25 (squares), N = 400, P/σm = 10 (downward triangles), N = 800, P/σm = 5 (triangles), and N = 160, P/σm = 4 (circles).”
