Figure F20. Example of remanent magnetization directions from AF demagnetization of archive half of Section 330-U1372A-14R-2. Directions were determined using principal component analysis (PCA). All PCA directions for this section have misfits below the threshold of PCA fitting quality. Open circles with error bars = piece-average directions, triangle = inclination from AF-demagnetized discrete sample. To avoid edge effects, data acquired within 4.5 cm of either piece end were filtered out.
