Graph of radiocarbon dating accuracy
The calibration curve itself has an associated error term, which can be seen on the graph labelled "Calibration error and measurement error".This graph shows INTCAL13 data for the calendar years 3100 BP to 3500 BP.
Simply reading off the range of radiocarbon years against the dotted lines, as is shown for sample t Variations in the calibration curve can lead to very different resulting calendar year ranges for samples with different radiocarbon ages.
Radiocarbon years ago may be abbreviated " The Northern hemisphere curve from INTCAL13.
As of 2017 this is the most recent version of the standard calibration curve.
It was unclear for some time whether the wiggles were real or not, but they are now well-established.
These were superseded by the INTCAL series of curves, beginning with INTCAL98, published in 1998, and updated in 2004, 2009, and, most recently, 2013.
