A three-column figure, presenting the output of the time-frequency analysis tool for the three-satellite case, using data from ST5 155, 094 and 224 satellites (after subtracting IGRF model) at the closest pass in time with the CHAMP track of Fig. 4. From top to bottom, filtered magnetic field, wavelet power spectrum, and magnetic latitude vs time. The bottom row at each column provide additional information about the satellites’ MLT position. Flagging of noisy segments and wave events in lower panels as in Figs. 2–4.
