Extended Data Fig. 9 | Comparison of bulk sound velocity from
diffraction and ultrasonic measurements. Shown is a comparison
of bulk sound velocity calculated from PVT EoSs, fitted to literature
diffraction data (solid curves) with 2σ uncertainties shown by shaded
regions, and only to that reported by Gréaux et al.^20 (dashed curves),
with bulk sound velocities calculated from ultrasonic measurements via
vbulk = (vP^2 − 4/3vS^2 )0.5 for data from Gréaux et al.^20 (squares) and this
study (circles). All curves and symbols are coloured for temperature
(colour scale at right).
