Figure 10. Filtered reflectancy series for the band between 17 and 25 k.y., shown for the last 1.2 m.y. Precession = variations in insolation resulting from long-term fluctuations in eccentricity and the changing perihel positions with respect to the northern solstice (taken from Berger and Loutre, 1991).
