Expanded record of a 5-s-long data segment, starting at 13:13:15 UT, on November 27, 2000, showing a sequence of individual chorus elements observed on both SC1 and SC2. The magnitude scale refers to electric field amplitude with 0 dB corresponding to 1 V/m/√Hz. The SC2 panel is repeated on the right to illustrate the differential Doppler shift. Also shown in the bottom right panel is the location (not shown to scale) of the spacecraft with respect to the two possible source locations (as derived from our analysis) along the field line. The small panel on the bottom left of this diagram shows the entire field to provide perspective.
