Figure 1
An example of a 14C calibration output plot from MatCal. The red shaded area indicates the 14C age normal distribution. The darker and lighter blue shading respectively indicates the 1 sigma and 2 sigma credible intervals of the calibrated age PDF. The darker and lighter grey shaded areas indicate the calibration curve 1 sigma and 2 sigma confidence intervals, respectively. The green error bars (only shown in the case of IntCal13) indicate the raw 14C data used to construct the calibration curve.
