The latter is arrived at using ( - log|(a-b)/a| - log|(a-b)/b| ) / 2 In the case of an inconsistent number of data points, a 3rd field is printed giving the difference (#points[file2] - #points[file1]). At the end of each of the 4 postfit tables is a line indicating the worst values in each column, the maximum absolute difference and minimum number of digits of agreement. They begin with a "!" and contain markers identifying the sort fields. The first numerical field in the SUMMARY line is a status flag, which indicates a 0 if no differences are found and 1 otherwise. Following are the number of outlier points counted in file1 and file2. The remainder of the SUMMARY line consists of the worst values (maximum absolute difference and minimum number of digits of agreement) from each table.
