Notes. We include the model name, the target nature, the proton and α flux amplitudes, their corresponding range of energy per nucleon, the irradiation time τirr and the dilution factor fmix. The latter two quantities are adjusted separately for each SEP model in order to best reproduce the observed composition of 2M13535604+4437076 (star “1”) or 2M22045404-1148287 (star “2”), as noted in the last digit of the model name.
