我们提出了一种简化的方法来校准放射性碳年代。我们使用样条通过树轮数据作为校准曲线，从而消除了很大一部分的实际数据点的统计分散。为了表示年龄范围，我们将BP年龄的+/- 1 sigma和+/- 2 sigma值转换为日历日期，并将其解释为68%和95%置信区间。这种方法绕过了将个体概率值从放射性碳转移到日历年龄的概念问题。我们已经调整了软件，使这种校准成为可能。
We propose a simplified approach to the calibration of radiocarbon dates. We use splines through the tree-ring data as calibration curves, thereby eliminating a large part of the statistical scatter of the actual data points. To express the age range, we transform the +/- 1 sigma and +/- 2 sigma values of the BP age to calendar dates and interpret them as the 68% and 95% confidence intervals. this approach bypasses the conceptual problems of the transfer of individual probability values from the radiocarbon to the calendar age. We have adapted software to make this calibration possible.
