Figure F19. A. Inclinations measured on archive halves (solid line) and discrete samples (open boxes). B. Interpreted magnetostratigraphy (see legend in Fig. F20). C. Maximum angular deviation angles for discrete subsamples. D. Vector length for discrete subsamples from PCA, where the vector length is the distance from the origin (zero magnetization) to the center of magnetization (analogous to the center of mass) for the measurements used to compute the PCA best-fit vector. This is a measure of the intensity of the best-fit vector.
