Calculate C14 ages from F14C values of radiocarbon dates.
Usage
F14CtoC14(F14C, er = NULL, decimals = 8, lambda = 8033)
Value
The radiocarbon ages from the F14C values. If F14C values are above 100%, the resulting radiocarbon ages will be negative.
Arguments
F14C
Reported mean of the F14C
er
Reported error of the F14C. Returns just the mean if left empty.
decimals
Amount of decimals required for the radiocarbon age. Quite sensitive, defaults to 8.
lambda
The mean-life of radiocarbon (based on Libby half-life of 5568 years)
Details
Post-bomb dates are often reported as F14C (between 0 at c. 55 kcal BP and 1 at c. AD 1950). Since software such as Bacon expects radiocarbon ages,
this function can be used to calculate radiocarbon ages from F14C values. The reverse function is age.F14C.
