Rotational analysis for the Sun. a) Solar VIRGO g+r light curve for more than 24 years, accounting for solar cycles 23 and 24. b) Wavelet power spectrum (WPS), where we adopt the Morlet wavelet. The color code corresponds to Rainbow+White, where black and white correspond to the highest and the lowest power, respectively. c) GWPS, which is the sum of power along the x-axis of the WPS (i.e., time). d) ACF of the light curve. e) CS, which is the product between the normalized versions of c) and d). The dotted lines indicate the three period estimates.
