μ189Os and cosmic ray uncorrected μ100 Ru for IAB iron meteorites. The uncertainties for multiple analyses of individual samples, where n < 3, are reported as the 2SD of the standard, or the sample, whichever was greater. The uncertainties for individual samples, where n ≥ 3, are the 2SE associated with the multiple measurements of the sample. Where n is the number of analyses of a single sample solution for (a) Ru and (b) Os.
