Add the ¹⁴C assays
Enter each AMS result with the rings it covers (ring 1 = innermost ring of SG-OAK-014), or paste a CSV in the assay table. Two or more ring-sequenced assays are needed.

Model
Exact posterior on a 1-yr grid. Assays are compared with the IntCal20 mean over their ring block. Prior range: —.
Miyake single-year anchor
Annual assays are scanned for an abrupt rise in ¹⁴C concentration: step ≥ 8‰, z ≥ 4, with ≥ 60% of the rise between two consecutive rings.
0 annual (single-ring) assays — at least 4 consecutive are needed.
The same assays drive the cross-dating canvas ¹⁴C overlay (key r), the combined multi-proxy date and the dossier.
