This excel file contains pressure-density values obtained from VISAR and X-ray diffraction data analysis for iron oxide (FeO) and magnesium oxide (MgO), as reported in the Nature Geoscience article: "Implications of the iron oxide phase transition on the interiors of rocky exoplanets", by F. Coppari et al (2021).

Prepared by LLNL under Contract DE-AC52-07NA27344.

Density values are obtained from X-ray diffraction data, pressure values are obtained from velocity interferometer data.
