A program for analyzing sediment-charcoal records with the goal of peak-detection to reconstruct "local" fire history.

A program that calculates sample ages and error estimates based on ²¹⁰Pb measurement and the assumptions of the Constant Rate of Supply model. The program also produces a spline-based chronology with confidence windows. Calculations follow  Binford 1990 (Calculation and uncertainty analysis of ²¹⁰Pb dates for PIRLA project lake sediment cores. Journal of Paleolimnology, 3: 253-267.)

*Documentation for this program coming*

Fit calibrated ¹⁴C dates and ²¹⁰Pb dates with a spline-based age-depth model, and estimate confidence intervals around the fit based on  Monte Carlo resampling of the original dates. For each Monte Carlo resampling, the age of each sample is picked randomly from  the PDF of the calibrated age. In the case of ¹⁴C dates, this avoids having to select a single age for each date.
