Mercury Interior Models consistent with the obliquity measurements by Margot et al. 2012 moment of inertia factor (moi) = 0.346) and Genova et al. 2019 (moi = 0.333). For a description of the models and the associated methodology please see Steinbrügge et al. 2020, GRL (in press). The data is structured in 5 folders containing models with an Fe-S and Fe-Si core. The central values for Margot et al. 2012 are consistent with a moment of inertia factor (moi) of 0.346+/-0.014. Note that no solutions have been found for 0.346+0.014. The central values for Genova et al. 2019 are moi=0.333 +/-0.005. Each individual interior model is stored in ascii format with the file name indicating the inner core radius. The label for all files is # Radius [km] # Density [kg/m3] # Pressure [GPa] # Temperature [K] # Light Element Content [wt.%] References Margot, J.-L., Peale, S. J., Solomon, S. C., Hauck, S.
