Notes: For all samples, principal component analysis (PCA) anchored to origin. N = number of points used for PCA, MAD = maximum angular deviation (Kirshvink, 1980), NRM = natural remanent magnetization, NRMχ = bulk susceptibility of NRM, MDF = median destructive field. AF = alternating-field demagnetization, TH = thermal demagnetization.
