Delta14CtoC14: Transform Delta14C into C14 age

In rice: Radiocarbon Equations

Transform Delta14C into C14 age

Description

Transform Delta14C into C14 age

Usage

Delta14CtoC14(Delta14C, er = NULL, t, roundby = NA)

Arguments

Delta14C	The Delta14C value to translate
er	Reported error of the Delta14C. Returns just the mean if left empty.
t	the cal BP age
roundby	Amount of decimals required for the output. Defaults to roundby=NA, no rounding.

Details

As explained by Heaton et al. 2020 (Radiocarbon), 14C measurements are commonly expressed in three domains: Delta14C, F14C and the radiocarbon age. This function translates Delta14C, the historical level of Delta14C in the year t cal BP, to C14 ages. Note that per convention, this function uses the Cambridge half-life, not the Libby half-life.

Value

The corresponding C14 age

Examples

  Delta14CtoC14(-10, 1, 238)
