De as a function of D<sub>0</sub> for each sample.

<p>The central De is calculated while the lowest D<sub>0</sub> values are progressively discarded. The grey dots represent the De for each grain as a function of the D<sub>0</sub> value of its growth curve. The black dots represent the central De while the grains with the lowest D<sub>0</sub> values are progressively discarded. The black line represents the cumulative number of grains (in percent of the total number of grains passing the criteria) that are saturated, as a function of their minimal D<sub>0</sub> value.</p>
