Table 1 Periods (in millions of years) corresponding to the highest peaks in the spectral analysis of six Phanerozoic time series (after Rampino and Stothers 1984; Rohde and Muller 2005; Omerbashich 2006) and compared to Row 3 and Row 5 harmonic predictions from the Sun (L = loop; LT = loop and tail;and L2T = loop and double tail)

From: The Sun-Earth connect 3: lessons from the periodicities of deep time influencing sea-level change and marine extinctions in the geological record
