Fig 8. GaussWM dialog of CalPal-software (version 2020.2), illustrating the stratigraphic age-modelling analysis of Sindos ¹⁴C-data.

Left: spreadsheet with input of data and results; program functions; tools for age-model construction; tools for statistical analysis. Right Upper: Graph showing on-screen (Monte Carlo run-time animation) the presently achieved best-fit position of the archaeological ¹⁴C-series in context with the selected calibration curve. Right Middle: Histogram showing the dating probability and precision of the step-wise expanded ¹⁴C-series. Right Lower: Statistical fit parameters are given as run-time series of the stepwise expanded sequence. Red = dating probability; Blue = dating precision; Green = simultaneously optimized precision and probability. Note: During run-time the GaussWM tables and graphs are continually refreshed (every ~3 secs). An explorative model analysis requires ca. 1–5 min run-time. Typical runs require 6–16 hours.
