In collaboration with Paul Blackwell, she devised a tailor-made Bayesian curve estimation method which was adopted by the IWG for making all of the 2004 internationally-agreed radiocarbon calibration curve estimates.
This paper reports on that work and on the on-going work that will eventually provide models, methods and software for rolling updates to the curve estimates.
The package also allows Bayesian analysis of sequences, phases, tree-ring sequences, age-depth models, etc. BCal: Online Bayesian radiocarbon calibration tool. Developed at the Department of Probability & Statistics, University of Sheffield (UK), this allows users to obtain calibrated dates on data sets entered via a Web browser.

Details Calibration of a radiocarbon age of 6550 ± 40 BP of a terrestrial sample from the Northern Hemisphere, using Int Cal04 calibration curve and Ox Cal program version 3.10.
The difference of the two curves (R) is ~400 yr on average.
