Notes. The correlation between the averaged shift and the activity proxy, the 10.7 cm radio emission flux, is measured with the Spearman rank coefficient ℛ. The symbol 𝒜 denotes the amplitude of the averaged shift, computed by taking the difference between the maximum and minimum of the data smoothed with a Savitzky-Golay filter. The shift amplitude was only evaluated for correlation coefficients strictly larger than 0.25.
