143 | 5.800 | Birch-Murnaghan (order unspecified) | — | Original | ||||||||||
| Why this differs from similar rows: Main-text fit: V0 fixed at 86.71 A^3, K_T0 and K_T0' both fitted freely from the room-T P-V-T data, yielding K_T0=143(4), K'=5.8(6); sibling Table 1 rows instead fix K0 or fit it differently. | ||||||||||||||||||

| Why this differs from similar rows: Table 1 row where K (=143) is fixed alongside V0 ('the value was fixed when calculated') and only K' (5.85) and thermal terms are fitted; sibling row instead lets K float (=142, K'=6.0). | ||||||||||||||||||

| Why this differs from similar rows: Table 1 2-D linear fit over 0-23 GPa and 300-900 K (includes a dK/dT term); sibling row fits only the room-temperature data (0-21 GPa, 300 K). | ||||||||||||||||||

| Why this differs from similar rows: Table 1 finite strain fit over 0-23 GPa/300-900 K with K' fitted freely (=5.55) while K0 stays fixed; sibling rows either fix K' too or let both K0 and K' float. | ||||||||||||||||||

| Why this differs from similar rows: Table 1 finite strain fit over 0-23 GPa/300-900 K with both K0 and K' fitted freely (K=134(7), K'=6.6(7)); sibling rows in the same range fix K0, K', or both instead. | ||||||||||||||||||
