The ε56Fecorr. and ε58Fecorr. have a second-order mass fractionation correction following a Rayleigh distillation as shown by Render et al. (2018). The δ56/54Fecorr. are corrected for resolved nucleosynthetic anomalies using ε56Fe (this is only done for Egg 2 mineral separates and A-ZH-1). The uncertainties shown represent either the long-term reproducibility (2SD) based on repeat analyses of the terrestrial standard during the measurement campaign or the 2SD of replicate sample analyses. For Marge, ε58Fe is not reported due to a large Ni interference in this sample.
