Notes: Principal component analysis (PCA) interval = level at which PCA analysis was performed. N = number of samples. 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. PCA quality: A = considered to be a reliable record of stable remanence, C = significant overlap between ChRM and drilling overprint results in less reliable inclination. Only a sample of this table appears here. The complete table is available in ASCII.
