Fig. 10.From: Hodograph method to estimate the latitudinal profile of the field-line resonance frequency using the data from two ground magnetometersShows the hodograph for the B37-B36 pair. The datapoints (small open circles) correspond to the B37-B36 data (asterisks) in the bottom two panels of Fig. 9 between the two vertical dashed lines. The data hodograph is too far away from a simple circular shape to make it meaningful enough to calculate f R (x) using the hodograph method.Back to article page
