Figure 29. Kivakka. Charts of time rows of the mean values of inclination I (on 9 samples). The second variant of recording. a - initial data (black line)and averaging by the 3rd order local polynomial in a running window of a radius of 20 counts (10 kyr); c - initial data (black line) and averaging by the 3rd order local polynomial in a running window of a radius of 10 counts (5 kyr); c, and d - difference between initial data and a smoothed curve.
