F14CtoDelta14C: Transform F14C into Delta14C

In rice: Radiocarbon Equations

Transform F14C into Delta14C

Description

Transform F14C into Delta14C

Usage

F14CtoDelta14C(F14C, er = NULL, t, roundby = NA, lambda = 5730/log(2))

Arguments

F14C	The F14C value to translate
er	Reported error of the F14C. 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.
lambda	Radiocarbon's mean-life, based on the Cambridge half-life

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 F14C values into Delta14C, the historical level of Delta14C in the year t cal BP. Note that per convention, this function uses the Cambridge half-life, not the Libby half-life.

Value

The corresponding Delta14C value

Examples

  F14CtoDelta14C(0.89, .001, 900)
