Northern Hemisphere atmospheric radiocarbon calibration curve for the period 0 to 50,000 yr BP.
1 |
A data frame with 3522 observations on the following 5 variables.
CAL.BP
Calibrated age in years Before Present (BP).
C14.age
C14 age in years BP.
Error
Error estimate for C14.age
.
Delta.14C
Delta.14C value in per mil.
Sigma
Standard deviation of Delta.14C
in per mil.
Deltal.14C
is age-corrected as per Stuiver and Polach (1977). All details about the derivation of this dataset are provided in Reimer et al. (2009).
