(v) "Database_IDPs&MMs_He&Ne_GFénisseEtAl_EPSL.xlsx", an exhaustive database containing all published light noble gas data (³He, ⁴He, and ²⁰Ne) measured in IDPs and MMs collected in the stratosphere and Antarctica; (vi) "ReferencesTable_3HeETFlux_GFénisseEtAl_EPSL.xlsx", a database of light noble gas measurements in Antarctica MMs. This dataset of He vs. MM mass is used here to convert ³He concentrations into dust abundances.
