Comparisons of radiocarbon concentrations from New Zealand and Tasmania trees. Radiocarbon concentration (D¹⁴C, 1 σ error bars) plotted against calendar age for the Pureora tanekaha tree FS066⁴ together with Northland kauri¹⁴ and Tasmanian huon pine¹⁵. It should be noted that the vertical axis title in HDK18’s Fig. 3 is incorrect—it should read D¹⁴C, as above, not Δ¹⁴C, which is age-corrected ¹⁴C concentration
