a
n is the number of analyses for Mo and Ru isotopic composition. The reported isotopic values reflect the average values obtained for each meteorite piece. Uncertainties reflect the largest (of n analyses) 2SD of the standards run during an analytical campaign (n ≤ 3) or 2SE (n > 3) of the sample values.
