Fig 8. Ten simulated radiocarbon dates for 1615 with ±15 radiocarbon years measurement uncertainties (Using the R_Simulate function in OxCal [23]) with the IntCal13 radiocarbon calibration curve (curve resolution 5 years) [22].

The effect of the reversal in the calibration curve is clear with much of the calibrated probability lying up to a century or more too early.
