Northern Hemisphere atmospheric radiocarbon for the pre-bomb period
Description
Northern Hemisphere atmospheric radiocarbon calibration curve for the period 0 to 50,000 yr BP.
Usage
data(IntCal09)
Format
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.
Details
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).
