Extended Data Fig. 2: Modelling the acoustic velocity of bridgmanite to derive Cij at 11.66 GPa.

Error bars are not shown when smaller than the symbols. Filled data points are the velocity data from Kurnosov et al.3; the dashed lines are velocity-fitting curves from Kurnosov et al.3; and the solid lines are velocity-fitting curves using the Cij derived from the covariance matrix analysis in this study. Red, VP; green, VS1; blue, VS2. The orientations of the crystal platelets are given in parentheses.
