a. Common period of overlap between TML001 and TML002 demonstrating similarity between the ring width sequences (t = 8.3; see the Table 1 caption for description of this statistic). The dotted line (TML) is the average of TML001 and TML002. b. Crossmatch between TML and Baltic3 (2021BLT2; Daly and Tyers 2022) across the common period of overlap (1410–1597 CE).
