Atmospheric South data for calibration of 14C age

As 14C years is not equal to calendar years because atmospheric 14C concentration varies through time. Hence, data in AtmosphericSouth_CalC14 allows a calibration for mid-latitude Southern Hemisphere atmospher reservoir.

Usage

data("SHCal13")

Format

A data frame with 3 variables.

CAL.BP

a numeric vector correpondig to calendar years (in ky) befor present

X14C.age

a numeric vector correponding to 14C age

Error

a numeric vector correponding to error arround 14C age measurement
