Evidence from the paper
'agreement has only recently been reached on the value of the bulk modulus (K0S = 253(3) GPa) [Sinogeikin et al., 2004; Li and Zhang, 2005; Vanpeteghem et al., 2006]'; 'within uncertainty of the currently accepted value for MgSiO3 perovskite (K0S = 253(3) GPa) from Brillouin and ultrasonic measurements [Sinogeikin et al., 2004; Li and Zhang, 2005]'
