SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema
How do I calibrate radiocarbon dates using the IntCal20 curve?▼

Calibrate conventional radiocarbon measurements against the IntCal20 curve to generate calibrated calendar-age probability distributions with median, sigma, and 95% HPD intervals.

What is Bayesian stratigraphic sequence modeling for archaeological dating?▼

Bayesian stratigraphic sequence modeling fits stratigraphically constrained radiocarbon dates using MCMC to generate posterior samples and per-layer summary statistics for multi-layer burial sequences.

How do I compute HPD intervals for calibrated radiocarbon ages?▼

Compute HPD intervals by extracting summary statistics like mean, median, and sigma from calibrated probability distributions, outputting 68% and 95% uncertainty intervals in calibrated years with cal BP to CE/BCE conversion.

Can I use wiggle matching for floating tree-ring sequences in geochronology?▼

Yes, wiggle matching estimates best-fit alignment for ring sequences with known inter-ring time gaps, applying floating tree-ring style calibration to radiocarbon measurements in geochronology scenarios.

Does radiocarbon calibration support the SHCal20 and Marine20 curves?▼

Yes, radiocarbon calibration supports loading and interpolating IntCal20, SHCal20, and Marine20 curve parameters to compute likelihoods for terrestrial and marine geochronology samples.
