Figure 2.4. (a) Thickness profile data for 16 tip-to-tip compaction band traces (>1,700
measurements). Position is normalized relative to center by the band half length and
thickness is normalized by the midpoint value. The curved line represents an ellipse
similarly normalized. The correlation index of the data to the ellipse is 0.79. (b) Plot of
midpoint thickness versus trace half-length for the 16 compaction band profiles, star
indicates CB shown in (c). Thickness generally increases with increasing length, but
along a decreasing trend. (c) Thickness profile for CB-A, the 24.75-m-long compaction
band trace featured in this paper. The curved line represents the least-squares best fit of
an ellipse to the data. The correlation index for this fit is 0.87.
