The values in Tables 2 and 4 are incorrectly duplicated. In Table 2, lines 1–15 are the same as lines 16–31. Lines 16–31 feature the correct formatting. In Table 4, lines 1–11 are the same as lines 12–22. Lines 12–22 feature the correct formatting. Please see the corrected Tables 2 and 4 here. The publisher apologizes for the error.
