Lattice parameters, unit-cell volume of Al-bearing superhydrous phase B and velocity data of different models with various depth/pressure

The lattice parameters for samples and velocity data of different models used in the under review paper, "Effect of Al-incorporation on the sound velocities of superhydrous phase B at high pressure and high temperature", submitted to the journal 'Geophysical Research Letters'. The lattice parameters of samples are obtained at room pressure and temperature conditions. Velocity data of different hydrous models are determined by sound velocity mensurement in SPring-8.
