The spatial wavelet spectra of 73 published spiral galaxies's rotation curves are computed and their associated scaleograms are presented. Scaleograms are used to detect and isolate local features observed in spiral galaxies's rotation curves. Although wiggles and bumps are usually interpreted as signs of recent and on-going merging, the analysis of the scaleograms reveals regular patterns consistent with the presence of large-scale modes throughout the disk.
