Wavelet planes highlighting the velocity substructure in the SN at different scales. The panels correspond to scales from j = 2 (panel a) to j = 5 (panel d). The colour bar shows only the positive coefficients, just like the solid-line contours, which are shown for different percentages of the maximum coefficient at levels from 10% to 90% every 10%, plus 5% and 99%. Additionally, the negative coefficients are represented by the dashed-line contour at the −1% level. With the values used (see text), the Sun would be located at (−11,−252) km s−1
