  1. Terms from column 4 (“N”) to column 16 (“δ(TR)”) as defined in Table 1. k: curvature. k = R−1, where R is the radius of the fitted circle to the data set (pTRM vs NRM); PI: paleointensity; σ: standard deviation of paleointensity. Specimen names in italic face correspond to specimens rejected for the average intensity calculation because of exceeding of at least one of the threshold values (underlined) set for the corresponding assigned Class
