- See the About link above for explanation of how cooked data is derived from raw
- calsigI: A calendar age uncertainty which is Independent of all other samples in the dataset, for example, a Uranium / Thorium date uncertainty.
- calsigD: A calendar age uncertainty which is Dependent on other samples in the dataset, for example a wigglematch uncertainty.
- calsigC: A calendar age uncertainty which is Cumulative. Counting errors and speliothem growth model uncertainties are examples.
- calseqno: A somewhat redundant field which defines the range of samples affected by a dependent error structure. When there is a dependent error it will be the same for all samples in a division of a dataset.
- raw.c14age: radiocarbon age BP uncorrected for reservoir age.
- raw.c14sig: The uncertainty in the c14 age reported by the radiocarbon laboratory.
- c14addsig: Additive c14 age uncertainty.
- c14mulsig: Multiplicative c14 age uncertainty (error multiplier).
- ReservoirAge: Local reservoir age of the ocean for marine samples or a Dead Carbon Fraction in speliothems.
- ReservoirSig: Uncertainty in the reservoir age.
