Initial Reports Volume 192 Chapter 5, Table T10. Paleomagnetic units A1-A4 and B1-B18. Notes: top = depth of the uppermost, base = lowermost basalt piece within each unit. N = number of ChRM determinations in a given paleomagnetic unit. Inc = mean inclination calculated using Kono's (1980b) statistics. k = precision parameter. alpha95 = 95% confidence angle. For paleomagnetic units with <3 ChRM determinations, performing Kono statistics is impossible; therefore, only the mean inclination is listed for these units.
