Revisiting the Question: The Cause of the Solar Cycle Variation of Total Solar Irradiance

<div>Partial wavelet coherence of the daily TSI and Mg II index (after eliminating the effect of sunspot area). The dashed black line indicates the COI where edge effects might distort the picture, and the 95% confidence level is shown as a thick contour, which is estimated by Monte Carlo method.</div>
