Fig. 4 | The probability of occurrence of various levels of additional 14C production (Q) related to a potential spike, based on the seven datasets from 1 to 970 CE. From top to bottom, each panel corresponds to a Q threshold ranging from 1 to 3.5 atom cm−2 s−1 yr−1. Years with a probability greater than 40% are indicated.

Single year measurements between 1560–1510 BCE from GrM (this study), along with ETH, AA (Pearson et al. Reference Pearson, Brewer, Brown, Heaton, Hodgins, Jull, Lange and Salzer2018, Reference Pearson, Wacker, Bayliss, Brown, Salzer, Brewer, Bollhalder, Boswijk and Hodgins2020b), and MAMS (Friedrich et al. Reference Friedrich, Kromer, Wacker, Olsen, Remmele, Lindauer, Land and Pearson2020) showing (a) 14C data (b) corresponding Δ 14C values.
