adjust.background: Adjust a radiocarbon age for background measurements

In rice: Radiocarbon Equations

Adjust a radiocarbon age for background measurements

Description

Calculate the radiocarbon age by adjusting it for a measured background. It is planned to update this function to more properly reflect calculations in the 14CHRONO lab.

Usage

adjust.background(y, er, bg, bg.er, realm = "C14")

Arguments

y	The age of the sample (in C14 by default, but can also be in F or pMC).
er	The error of the date.
bg	The background measurement. Should be in the same realm as that of the sample.
bg.er	The error of the background measurement. Should be in the same realm as that of the sample.
realm	Type of radiocarbon age. Can be in 'C14' (default), 'F14C' or 'pMC'.

Details

Radiocarbon ages are measured using a series of standards and backgrounds, and the raw values are then corrected for these background values. Backgrounds are >0 (in F14C) owing to contamination in even the cleanest lab.

Value

The background-adjusted age.
