Hodograph method to estimate the latitudinal profile of the field-line resonance frequency using the data from two ground magnetometers

Earth, Planets and Space

Table 1. Shows the locations of the BEAR stations used in this paper. Longitudinal distances of the stations from the 105° magnetic meridian are less than 0.7°. See text for more details.
