Note that double clicking on a command also allows you to edit it

  • 編年モデル: shows a box model with the oldest events shown first (at the top)
  • 層序モデル: is reversed so that the oldest events are shown at the bottom
  • リスト: shows a heirarchical list of commands
  • コード: shows the actual code in an editable form - no other editing methods work in this mode

Note in all cases except code groups can be expanded and contracted to make the model easier to work with

  • Resolution: bin size for probability distributions
  • Curve options
    • Cubic: interpolation between curve points (otherwise linear)
    • Include raw data: required if you want this in your plots
    • Use F14C space: calibration comparisons are made in F14C rather than BP
  • Whole (foruits): gives only one range (floruit if using probability method)
  • Intercept method: for 14C calibrations (otherwise probability method)
  • Convergence data: include if you wish to plot
  • Uniform span prior: special prior factors for use with multiple phases
  • MCMC iterations: select higher number to ensure conversion

Specific atmospheric curves can be selected. See help on calibration curves.

An exponential reservoir time constant can be enetered where turnover is slow relative to the resolution.

Marine components can be entered in any proportion (select 100% for fully marine). You will need to set a ΔR offset for local effects. See help on calibration curves for links to database of values.


Select required type of model

  • Phases: groups of events that have do not have their relative order defined
  • Sequences: groups of events where the relative order is known
  • 14C date combination: combine several 14C dates
  • Dendro wiggle match: groups of events where the exact age gap between events is known (eg tree rings)
  • Deposition model: events from a context where linear or Poisson deposition rate can be assumed
  • Exponential distribution: events exponentially distributed in time (exponential rise or fall)
  • Ramped distribution: events ramping linearly up or down in probability over a period
  • Normal distribution: events with an expected Normal or Gaussian distribution
  • Outlier model: model to use with outlier analysis

  • Rise/Fall: defines whether the events are rising or falling in probability over the period
  • Ordered: defines whether the events within the group are in a particular sequence
  • Tau_Baoundary which is evaluated, is one exponential time constant away from the end point of the exponential- the events in the group will normally straddle this value

正規分布モデル
グループ内順位
  • Ordered: defines whether the events within the group are in a particular sequence
  • The Sigma_Boundaries which are evaluated, are +/- 1σ for the normal distribution - the events will usually spill outside these 'boundaries'

  • The name can be used to refer to a specific model in Outlier() statements.
  • The distribution function defines the distribution of the outliers.
  • The overall scale of the outliers must be defined - this can be left wide from between 100 to 104 which should cover most eventualities. The distribution is in powers of 10.
  • The types of outlier allowed are "t" for time, "r" for radiocarbon and "s" for possibly underestimated standard deviations.
