  1. Accelerator mass spectrometry (AMS) measurement errors are at 1 s level, including the statistical (counting) error and the error due to normalization of standards and blanks. The error weighted average 10Be/9Be full-process blank ratio is (2.37 ± 0.62) × 10–15. 26Al/10Be ratios were calculated with the CRONUS-Earth exposure age calculator and were referenced to 07KNSTD (http://hess.ess.washington.edu/math/(v.2.3); Balco & Rovey, 2008 and update from v. 2.2 to v. 2.3 published by Balco in June 2016)
