| Why this differs from similar rows: V0 fitted freely (Bayesian prior) from reanalyzed Tange et al. (2012) data, giving V0=162.12, K0=262.3; differs from sibling's fixed-V0 conditional fit. | ||||||||||||||||
| Bridgmanite |

300 K | 162.5 ų Unit cell |
253.200 | — | Vinet | — | Original | ||||||||
| Why this differs from similar rows: Conditional fit with V0 fixed to 162.5 (typical measured value) rather than fitted freely, yielding a different K0=253.2; sibling row fits V0 freely. | ||||||||||||||||

| Why this differs from similar rows: Cites Fiquet et al. [2000] (253-259 GPa depending on whether heated data included); V0 fixed to a measured volume; sibling row cites a different original study (Mao et al. 2011). | ||||||||||||||||

| Why this differs from similar rows: Cites Mao et al. [2011] (259.6 GPa); V0 fixed to a measured volume per that study; sibling row cites a different original study (Fiquet et al. 2000). | ||||||||||||||||
