Fig. 6From: Spatial scale of geomagnetic Pc5/Pi3 pulsations as a factor of their efficiency in generation of geomagnetically induced currentsParameters of the event 2 pulsation in the E–W direction: a \(B_Y\) waveforms at KEV (magenta) and KIL (green); b normalized PSD spectra; c E–W spectral coherence for \(B_Y\) (solid) and \(B_X\) (dashed); d E–W PSD ratio for \(B_Y\) (solid) and \(B_X\) (dashed)Back to article page
