The columns show KLR and GrA laboratory code numbers, δ¹³C in ‰, sample material, ¹⁴C activity ratio corrected for isotope fractionation in %, its standard deviation, ¹⁴C age in BP including its standard deviation, and calibrated age ranges in BCE at 1σ and 2σ confidence intervals. The ¹⁴C dates are calibrated with the latest calibration curve IntCal20 [32]. See text for details
