Wavelet coefficients and scales obtained by decomposing a normalized initial image (in this case, an AIA 193-channel base difference) after thresholding and shifting so that the values fit into [0, 1] interval. Left panels: Wavelet coefficients at decomposition levels 0, 2, 4, 6. Right panels: Corresponding wavelet scales at the same decomposition levels.
