AWESOME (Murphy et al. 2009a) analysis of the substorm in 2008-03-05/06:04:20 UT, run from 05:55:00 UT. Displayed in the figure are wavelet-derived power spectra as a function of time and wavelet period (s) or j (wavelet basis). The colours represent normalised wavelet coefficients, whereby black represents wavelet coefficients below the pre-determined threshold for each j and yellow-orange-red-white are coefficients rising above the threshold in increasing amplitude
