SHCal13 Data Sets

A summary of the datasets used for SHCal13 is given below with references to the original datasets. These are catalogued by the institute where the 14C measurements were made in some cases and in others by the first author on the publications.
Dataset number is a historical construct and makes no reflection on the date of publication. Lab codes can be found on the Radiocarbon website at www.radiocarbon.org.
