| Why this differs from similar rows: This study's free-K' fit (Table 2), K'=4.0(3) refined rather than fixed; sibling row is the fixed-K'=4 fit to the same data, giving a slightly different K0 and V0. | ||||||||||||||

229 | 4 | Birch-Murnaghan (order unspecified) | Pt (Fei et al. 2007) | Original | ||||||
| Why this differs from similar rows: This study's fixed-K'=4 fit (Table 2, K' marked as fixed); sibling row instead lets K' vary freely in the fit, giving a slightly different K0 and V0. | ||||||||||||||
