Comparison of the measured (symbols with error bars and dashed grey line) and modelled (histograms) ratios (a) ⁶⁰Fe/Fe, (b) ²⁶Al/Al, (c) ⁵³Mn/Mn, and (d) ²⁴⁴Pu/⁶⁰Fe from our fiducial simulation as a function of age of the respective reservoir. The inlay in panel b shows a magnification of the boxed area. All data, except ²⁴⁴Pu/⁶⁰Fe, are not corrected for radioactive decay. The crust ages of Knie et al. (2004) and Fitoussi et al. (2008) have been updated to account for the latest half-life of ¹⁰Be (; Korschinek et al. 2010) used for the dating. For the Fimiani et al. (2016) lunar data included in panel a, which for reasons of micrometeoritic gardening on the lunar regolith cannot be resolved better than about 8 Myr in time, we use the mean value determined by Ertel et al. (2023).
