IntCal20 {SoilR}

The IntCal20 northern hemisphere radiocarbon curve for the 0-55,000 yr BP period

Description

Atmospheric radiocarbon calibration curve for the period 0 to 55,000 yr BP for the northern hemosphere. This is the most recent update to the internationally agreed calibration curve and supersedes IntCal13.

Usage

data(IntCal20)

Format

A data frame with 9501 rows and 5 variables.

CAL.BP

Calibrated age in years Before Present (BP).

C14.age

C14 age in years BP.

Sigma.C14.age

Standard deviation for C14.age.

Delta.14C

Delta.14C value in per mil.

Sigma.Delta.14C

Standard deviation of Delta.14C in per mil.
