ISM ratios calculated (using equation (2)) and isolation times for s-process short-lived radionuclides using the Monash models

Uncertainty factors are 1σ equivalent (that is ±1σ = 68.2%) to represent the probability distributions shown in Extended Data Fig. 4. Choice of δ and uncertainty factors are described in the text based on refs. ^18,54. ESS ratios (with 2σ uncertainties) are taken from ref. ¹ and τ values from ref. ¹⁷. Note that we revised the s-process production ratios P to those from Monash AGB models computed with the most recent nuclear inputs, relative to the yields used in ref. ¹⁸. The stable s-process fractions are taken from the Monash GCE models of ref. ¹⁸, except for ²⁰⁴Pb, which is an s-only isotope.
