The radiocarbon ages of dendrochronologically-dated wood samples, each covering 10 years, are now available for the cal AD 1950–6000 BC age range. The decadal calibration curve constructed from these data comprises 1) the previously published AD 1950–2500 BC portion (Stuiver & Becker 1986), to which minor 14 C age corrections were applied, and 2) the new 2500–6000 BC extension.
Stuiver et al. (Fri,) studied this question.
