Figure 24. The first variant of recording the behavior of the geomagnetic field declination and inclination. Monchegorsk intrusion; 61m section, sampling every 1-2 m (ch). Points - initial data; line - averaging result ( H =0.25) and transition to a uniform step in time (Dt = 0.5); thick blue line - assessment of the adaptive trend with the help of a local-polynomial smoothing by the 3rd order polynomial in a running window of a radius of 20 counts (10 kyr). Time row D, b) result of subtraction of the trend (D ), c) wavelet diagram of the remainder after subtraction of the trend (D ); d) time row I ; e) result of subtraction of the trend (I ); f) wavelet diagram of the remainder after subtraction of the trend (I ). Lga - logarithm of the time scale (period).
