Fig. 14From: Substorm and pseudo-substorm Pi2 pulsations observed during the interval of quasi-periodic magnetotail flow bursts: A case study(a) The power spectrum of the H component from KAK and the stations of 210 MM network for event D, (b) interstation coherence, (c) amplitude ratio, which is defined as the square root of other station H to KAK H power ratio, and (d) cross phase for the H component of event D.Back to article page
