d radiocarbon ages. The steps for each 14C age are approximately as follows:
1) Create a grid of ages covering the range of the calibration curve
2) Calculate the probability of each age according to the 14C age, the standard deviation supplied and the calibration curve
3) Normalise the probabilities so that they sum to 1
4) Remove any probabilities that are less than the value given for eps
Multiple calibration curves can be specified so that each 14C age can have a different curve. For ages that are not 1
