| C14.Age |
int |
Uncalibrated years BP |
| C14.SD |
int |
Standard deviation |
| C14ID |
int |
Unique identification code for each C14 sample |
| CitationID |
varchar |
See citation table for the strict character code. |

| LabID |
varchar |
Unique Laboratory identification number. Lab suffixes must be in the C14laboratories table, which end with a hyphen. This is important as labcodes are automatically checked by string splitting on the first hyphen. Note, there are cases where multiple hyphen legitimately exist in a labcode (e.g. OxA-X-2135-46). Other non-standard characters are also permitted, such as ‘.’ or ‘/’. Case sensitivity is important, for example, prefix GD- and Gd- are two different laboratories. Spaces are NOT permitted, therefore rare occasions such as 'GIF FG 39a' will be automatically assigned 'GIFFG-39a' |
