Compression data for volatile-bearing and volatile-free pyrolite melts

Pressure-volume-density data for volatile-bearing and volatile-free pyrolite melts, separated as individual Excel sheets with the composition and temperature in the title of each sheet. As noted in the headers of each sheet, the first column is the length of the cubic supercell (units: Å), the second column is the volume of the supercell (units: Å3), the third column is the density (units: g/cm3), the fourth column is the pressure (units: GPa), the fifth column is the standard deviation on pressure (units: GPa), the sixth column is the temperature (units: K), and the seventh column is the standard deviation on temperature (units: K). Standard deviations on pressure and temperature were determined from the fluctuations of the simulations.
