Year-to-year changes in \(T_{yy}\) between KNY and MMB at a frequency of 9/30,720 Hz. a\(T_{yy}\) for KNY/MMB. The circles are derived from raw geomagnetic data, and correspond to the light-blue dots in Fig. 7e. The diamonds/squares/triangles in 2004 are derived from the reconstructed data using only Basis vector 2/Basis vector 6/Basis vectors 2 and 6, respectively. b\(T_{yy}\) for MMB/KNY. The circles are derived from raw geomagnetic data, and correspond to the light-blue dots in Fig. 7f. Note that the vertical axis of b is reversed
