rampedpyrox.RpoIsotopes.kie_correct

RpoIsotopes.kie_correct(model, ratedata, DE=0.0018)[source]

Method for further correcting d13C values to account for kinetic isotope fractionation occurring within the instrument.

Parameters:
  • model (rp.Model) – rp.Model instance containing the A matrix to use for inversion.
  • ratedata (rp.RateData) – rp.Ratedata instance containing the reactive continuum data.
  • DE (scalar) – Value for the difference in E between 12C- and 13C-containing atoms, in kJ. Defaults to 0.0018 (the best-fit value calculated in Hemingway et al., Radiocarbon, 2017).

Warning

UserWarning
If already corrected for kinetic fractionation
