Columns 1-4 give the dates in several redundant " " formats. Column 5 below gives monthly isotope concentrations in per-mil. This is the " " standard version of the data most often sought. The monthly values have been adjusted " " to 24:00 hours on the 15th of each month. Column 6 gives the same data after a seasonal " " adjustment to remove the quasi-regular seasonal cycle. The adjustment involves " " subtracting from the data a 4-harmonic fit with a linear gain factor. Column 7 is a " " smoothed version of the data generated from a stiff cubic spline function plus 4-harmonic " " functions with linear gain. Column 8 is the same smoothed version with the seasonal " " cycle removed. Column 9 is identical to Column 5 except that the missing values from " " Column 5 have been filled with values from Column 7. Column 10 is identical to Column 6 " " except missing values have been filled with values from Column 8.
