Calibrated dates according to OxCal38 based on the NHZ2 calibration curve32. All calibrated dates are within the 1σ range, probabilities are presented as percentages. Where the 2σ range is shown, it is presented in red. From the possible date ranges suggested by radiocarbon, we present our subjective likely option in the last column, based on the radiocarbon probability, as well as the location of the sample (e.g. consecutive samples must be in chronological order, correlation to estimated ring count and ring growth patterns).
