Default parameters
The R13 value of the PDB reference. Defaults to 0.01118, from Chang and Li, 1990.
The R18 value of the PDB reference. Defaults to 1.008751, from Coplen et al., 1983.
The R17 value of PDB (g). Defaults to 0.0003931, from Assonov and Brenninkmeijer 2003, re-scaled by Brand, 2010.
The R18 value of PDB (g). Defaults to 0.00208839, derrived from Baertschi, 1976, calculated by Brand 2010 eq. 2.
Isotopic fractionation of \(^{17}\)O. Defaults to 0.528, from Barkan and Luz, 2005.
The difference between the expected \(\delta^{17}\)O (\(\delta^{18}\)O\(-\lambda*\delta^{18}\)O) and the actual \(\delta^{17}\)O value.
