532 nm reflectivity along the principal Hugoniot. We plotted our calculated reflectivity (with a one-σ error bar) in the different phases of a MgO, b SiO2, and c MgSiO3 along their respective Hugoniot curves as described in Fig. 1. We added previous numerical results for MgO15, and systematically compared with available experimental results26,28,33,34 including their uncertainty
