Data for the De estimates of the quartz grains.

N: number of measured grains; saturated: number of grains that were rejected because of saturation; n1: number of grains that passed all the rejection criteria before D0 selection is applied; n2: number of grains that passed all the rejection criteria including D0 selection; D0: threshold for the D0 value; OD: over-dispersion calculated from the central age model; sigma_d: dispersion calculated from the average dose model.
