  1. * AMS measurements were performed at LLNL in 2002 for REM1 and at PrimeLab in 2005 for REM3, 4 and 5. They were normalized with the KNSTD reference as defined for the CRONUS-Earth online calculator v2.2 for standards prepared in 2002 and 2005 from ICN solution (Nishiizumi et al. 2007; NIM-B v. 258, p. 403)

  3. $Age is Lal (1991)/Stone (2000) time-depended production model calculated using the CRONUS-Earth online calculator (http://hess.ess.washington.edu/) version 2.2. Error on age is the external
  4. Uncertainty that includes both error on the nuclide concentration and error of model age used (Balco et al. 2008)
