Evidence from the paper
Table 1: K_S (GPa) = 253(2); K_S' = [4.4(10)]. Footnote a: 'The values in square brackets are the original results for MgSiO3 from Li and Zhang [15]'. Text: 'the pressure and temperature derivatives of the elastic bulk and shear moduli for the MgSiO3 perovskite have been determined by simultaneous measurements of P and S wave velocities and density to 9.2 GPa and 873 K [15].'
