radiocarbon-dating

What problem does it solve?

This Skill solves the problem of converting raw radiocarbon (14C) measurements into calendar-age estimates with credible uncertainty intervals. It also addresses the need to model multiple dates together using stratigraphic ordering constraints and to report results in publication-ready conventions.

Core Features & Use Cases

• Radiocarbon calibration: Calibrates single dates against IntCal20, SHCal20, or Marine20 curves to produce a calibrated probability distribution.
• Bayesian sequence modeling: Fits a stratigraphically constrained set of dates using MCMC to generate posterior samples and summary statistics per layer.
• Wiggle matching support: Estimates best-fit alignment for ring sequences with known inter-ring time gaps (floating tree-ring style calibration).
• Uncertainty reporting: Computes summary statistics (mean/median/mode/sigma) and HPD intervals (e.g., 68% and 95%) in calibrated years, including cal BP to CE/BCE conversion.

Quick Start

Use the radiocarbon-dating skill to calibrate the measurement 2850 ± 35 BP against the IntCal20 curve and return calibrated median, sigma, and 95% HPD intervals.
