Figure F3. Match between Northern Hemisphere summer insolation (65°N) and gamma ray attenuation (GRA) density (detrended) at Site 1237 from 2.1 to 6.0 Ma. Comparison of orbital precession and obliquity with the 21- and 41-k.y GRA filter outputs, respectively. Sedimentation rates are corrected for ash layers.
