| Why this differs from similar rows: Refit of Mao et al. [1989] DAC data weighting remaining points equally, low-pressure amorphized data excluded; sibling rows use different weighting/exclusion schemes on same data. | ||||||||||||||

282 | 4 | Birch-Murnaghan (order unspecified) | — | Original | ||||||
| Why this differs from similar rows: Refit of Mao et al. [1989] DAC data using the entire data set weighted by pressure uncertainties; sibling rows instead exclude certain low-pressure points or weight equally. | ||||||||||||||

| Why this differs from similar rows: Refit of Mao et al. [1989] data excluding points below 1 GPa (likely amorphization), same weighting as row 508; other sibling row weights all points equally instead. | ||||||||||||||
