Radiocarbon Calibration in the Anglo-Saxon Period: Ad 495–725
Open accessAbstract
Radiocarbon dating has been rarely used for chronological problems relating to the Anglo-Saxon period. The “flatness” of the calibration curve and the resultant wide range in calendrical dates provide little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology have, however, created the possibility of refining and checking the established chronologies, based on typology of artifacts, against 14 C dates. The calibration process, within such a confined age range, however, relies heavily on the structural accuracy of the calibration curve. We have therefore re-measured, at decadal intervals, a section of the Irish oak chronology for the period AD 495–725. These measurements have been included in IntCal04.

Laboratory error multipliers for other legacy datasets were left at the 2004 values, except for Belfast and Waikato where intra-laboratory multipliers had already been included in reported uncertainties; for these datasets multipliers were set to 1 to avoid applying them twice.
“The laboratory error multipliers for the other legacy datasets were also left at the 2004 values with the exception of the more recent data from Belfast and Waikato where intra-laboratory multipliers had already been included in the reported uncertainties (McCormac et al. 2004; Hogg et al. 2009; datasets 2/1, 2/2, 3/1 and 3/2). The laboratory error multipliers for these datasets were therefore set”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
