Evidence from the paper

Table 1: 'MgO ... B0 (GPa) 141 ... B0'=B'_{T0} 4.15 ... Parameters B0, α0, δ0, and B_{T0} are taken from Anderson et al. [3, 10].' Text: 'Values of B0, α0, and δ0 are taken from the experimental data at initial temperature T0 = 1000 K [3, 10]' and 'We have taken B0'=4.0 except for MgO and Al2O3, whose values are those determined from the data on density [3, 10].'
