Figure F74. A–H. Representative Zijderveld plots from archive-half cores, Hole U1374A. Solid circles = projections of vector endpoints onto the horizontal plane, open circles = projections onto the vertical plane. Red arrows = best-fitting principal component analysis (PCA) direction calculated automatically, pink arrows = rejected PCA directions (these correspond to pink symbols in Fig. F73). NRM = natural remanent magnetization. Boxes contain treatment level for PCA fit (A = anchored to origin, F = free of origin) and calculated misfit (see “Paleomagnetism” in the “Methods” chapter [Expedition 330 Scientists, 2012a]).
