Wavelet analysis results for BP3. Top: normalized light curves (black) integrated between two lines (such as between green and cyan lines for a, between green and magenta lines for b) in Fig. 3a, and slow-varying components (green). Middle: rapidly-varying components. Bottom: Morlet wavelet spectra of the rapidly-varying components in panels c and d, a significance level of 99% is outlined by the magenta line.
