Evidence from the paper
Table 2. Parameters of equations of state for pressure scales. MgO: V0, cm3/mol = 11.248; K0, GPa = 160.3; K′ = 4.25; k = 5. 'The parameters of equations of state for gold, periclase, and platinum, which are pressure scales in the determination of the P–V–T properties of minerals, are shown in Table 2.' 'To bring these measurements into consistency with our scales (Sokolova et al., 2013), pressure was recalculated with the use of the equation of state for MgO from Table 2.'
