- ARM00, initial ARM0 intensity after LTD; Nhys, number of chips for the hysteresis measurements; Brc/Bc, Mrs/Ms, sample-averaged ratios of coercivity of remanence (Brc) to coercive force (Bc) and saturation remanent magnetization (Mrs) to saturation magnetization (Ms); LTD, LT demagnetized fraction of ARM0; anisotropy ratio, ratios of ARMTRM direction to ARMNRM direction before laboratory heating; Hc, the coercivity interval taken for the linear segments; slopeA1, slopeA2, slopes of ARM spectra for Hc in the ARM0-ARM1 and ARM1-ARM2 diagrams; slopeN, slopeT, slopes of the linear segments in the NRM-TRM1* and TRM1-TRM2* diagrams; fN, fT, NRM and TRM1 fractions of the linear NRM-TRM1* and TRM1-TRM2* segments; rN, rT, correlation coefficients of the linear NRM-TRM1* and TRM1-TRM2* segments; F, calculated paleointensity; ΔAIC, AIC difference between linear and quadratic fit (Yamamoto and Tsunakawa, 2005); Numbers in parentheses indicate out of the selection criteria; Numbers in italic are averaged values with their 1 σ for the sample groups.
