Figure F5. Spectral analysis of (A) eccentricity and the biostratigraphic (BIO) age model and of (B) eccentricity and the tuned core magnetic susceptibility (TCMS) age model. The following apply to the BIO age model: bandwidth = 0.00131, number of lags = 2278, step = 2 k.y. The following apply to the TCMS age model: linear trend was removed, bandwidth = 0.00139, number of lags = 2149, step = 2 k.y.
