The IntCal20 Northern Hemisphere radiocarbon age calibration curve
on a calendar grid spanning from 55,000–0 cal yr BP
(Before Present, 0 cal yr BP corresponds to 1950 CE).
Note: This dataset provides \({}^{14}\)C ages and F\({}^{14}\)C values
on a calendar age grid. This is different from the \({}^{14}\)C ages
and \({\Delta}^{14}\)C values provided in oxcal .14c files.

A data frame with 9,501 rows and 5 columns providing the IntCal20 radiocarbon age calibration curve on a calendar grid spanning from 55,000–0 cal yr BP:
- calendar_age
The calendar age (in cal yr BP)
- c14_age
The \({}^{14}\)C age (in \({}^{14}\)C yr BP)
- c14_sig
The (1-\(\sigma\)) uncertainty in the \({}^{14}\)C age
- f14c
The \({}^{14}\)C age expressed as F\({}^{14}\)C concentration
- f14c_sig
The (1-\(\sigma\)) uncertainty in the F\({}^{14}\)C concentration
