Fig.kzr3: 200 Ka series of Potassium/Zirconium (K/Zr) ratio and (central plot) its enlargement relative to the first 50 Ka, both relative to 3-points step (i.e. here 1st, 4th, 7th ... points of the original series have been selected). The bottom plot is the Lomb spectrum (periodgram) of the 200 Ka series (upper plot) and shows a spectral maximum of the Orbital precession at 23.7 Kyr. A possible Obliquity signal is the spectral maximum at 47 Kyr (instead of the canonical 41 Kyr) while the 100 Kyr Eccentricity peak does not appear at all.
