Atmospheric radiocarbon for the 0-50,000 yr BP period

Description

Atmospheric radiocarbon calibration curve for the period 0 to 50,000 yr BP.

Usage

data(IntCal13)

Format

A data frame with 5140 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. (2013).
