Comparison of data from the neutron imaging and hanging water column experiments: (a) average water contents <θ>, (b) average water contents with neutron data corrected based on oven-dried sample, and (c) average relative saturations <S>. In all three cases, the 95% confidence intervals for individual points are not shown because they were smaller than the symbols used. Dashed line is the 1:1 relationship (closed circle: drying, open circle: wetting).
