Why this differs from similar rows?

Cites literature parameter set of Jackson and Rigden [1996] (K'=4 assumed per footnote); sibling row cites a different original study (Fiquet et al. 2000).

Evidence from the paper

Table 2 (Jackson, MgSiO3 Perovskite): V0 = 24.43 cm3 mol-1, K_T0 = 262 GPa, K'_T0 = 4.0 (footnote b: Assumed value). The thermoelastic parameters for MgSiO3 perovskite are from Jackson and Rigden [1996].
