Small aliquot data. N = number of aliquots measured, n = number of aliquots used for De calculation, OD = overdispersion, De - CAM = equivalent dose calculated using the Central age model by Galbraith et al. (1999), A = to select aliquots for De calculation conventional rejection criteria were applied as described in chapter 2, B = individuals Des were determined using an early background and conventional rejection criteria were applied, C = conventional rejection criteria were applied and additionally all aliquots with FRnat ≠ FRreg were excluded, D = conventional rejection criteria were applied and additionally all aliquots with FRnat and FRreg < 15 were excluded.
A: Conventional approach
B: EBG approach
C: FRnat = FRreg approach
D: FR > 15 approach

Single grain data. N = number of grains measured, n = number of grains used for De calculation, OD = overdispersion, Skew of De distribution following Bailey and Arnold (2006), De - CAM = equivalent dose calculated using the Central age model by Galbraith et al. (1999), E = to select aliquots for De calculation conventional rejection criteria were applied as described in chapter 2, F = individuals Des were determined using an early background and conventional rejection criteria were applied.
