This is a collection of pressure, volume, and temperature data for (Mg,Fe)SiO3 post-perovskite collected in laser-heated diamond anvil cells. The volumes and temperatures are collected from previous studies, and the pressures are reevaluated according to the internally consistent pressure scale of Dorogokupets and Dewaele (2007). A Monte Carlo sampling routine was used to propagate uncertainty from the measured volumes and temperatures, as well as uncertainties in the pressure scale parameters, to the final pressure uncertainties.
