RM = Rome laboratory, OT = Otago laboratory. AF = alternating field demagnetization. NRM = natural remanent magnetization, ChRM = characteristic remanent magnetization. MAD = maximum angular deviation. Steps: demagnetization steps included for ChRM calculation in mT for AF, or = anchored to the origin. Class = quality ranking for demagnetization data: 1 = high, 2 = intermediate quality, 3 = unreliable, 4 = no direction calculated.
