Why this differs from similar rows?
Model BM3S: global inversion includes Saxena et al. [1999] static data, excludes Fiquet et al. [2000]; sibling row (BM3F) uses opposite data selection.

Table 4. EoS Parameters for Solid Phases: Perovskite, Model BM3S, V, Å3 162.35, K0S, GPa 254.7(7), K'0S 4.26(3); 'we have renormalized all the volumes from static P-V-T data used in our modeling to a value of V0 = 162.35 Å3 [Horiuchi et al., 1987]'; 'Thus V0 is the only fixed parameter in our models'
