Note: The bulk siderophile element concentrations are calculated via mixing of rim and core with a certain proportion (roungly 1:9 in thickness for M1 assumed as an ideal spherical globule) that meets the bulk Ir concentration determined using isotope dilution. The calculated HSE concentrations are in less than 10 % differences from the bulk isotope dilution values.
