SHCal20 calibration curve
Description
The SHCal20 Southern 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 SHCal20 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
