adjust.background: 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")
Value
The background-adjusted age.
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.
