Notes: NRM = natural remanent magnetization. Inc = inclination of characteristic remanent magnetization determined by principal component analysis. Demag = demagnetization. A = alternating field. N = number of measurements used for principal component analysis. Steps = demagnetization steps used for principal component analysis. MAD = maximum angle of deviation (Kirshvink, 1980). Mean colat = group mean colatitude. Std = standard deviation of group mean colatitude. N colat = number of colatitudes used to calculate group mean. * = datum not used in average colatitude calculations. Group averages are shown at the far right; underscores show the division of groups. † = sample showing anomalous inclinations (see text).
