Notes: Principal component analysis (PCA) interval = level at which PCA analysis was performed. N = number of points. Decay type: A = anchored to origin, F = free of origin, + = includes origin as point. MAD = maximum angular deviation. PCA (%) = percentage of natural remanent magnetization intensity. This table is also available in ASCII.
