Correlations among Baeg-nyong (BN-1), Dongge (DA) and Heshang (HS-4) records. (a) Visible comparison among millennial-scale events (MSEs) represented by BN-1, DA and HS-4 records. Vertical grey bars describe timings of MSEs from plural Chinese records2,3,4. Light orange vertical bars indicate timings of MSEs from BN-1 record. (b) Correlation between BN-1 and HS-4 records. Some data subtracted from original datasets to produce similar time-resolution records within 5 years of the maximum age difference between both records. Note that 0.39 of Pearson correlation coefficient was produced between two records. This value was increased when both records are averaged by 3-points running means (Supplementary Fig. S5). Small black rectangles indicate MSEs reported from both of HS-43 and D1/D2 (Dark Cave)4 records. (c) Correlation between BN-1 and DA records. All processes are same to the case of (b). Small black rectangles indicate MSEs reported from DA record2.
