Notes: Directions are reported in the core reference frame. Demag = demagnetization. R = reversed polarity, H = polarity uncertain, N = normal polarity, D = drilling-induced magnetization. F = free of origin, A = anchored. MAD = maximum angular deviation. * = not suitable for reorientation studies (poorly defined direction, drilling overprint, or normal polarity of uncertain origin). This table is also available in ASCII.
