| Why this differs from similar rows: Table 2 preferred Vinet-form fit, KT0/K'T0 free, V0 fixed to Tange et al. [2009b]; sibling row is an alternative fit additionally constrained by external KS0 = 253 GPa. | ||||||||||||||

| Why this differs from similar rows: Alternative fit constraining KS0 to 253 GPa from Brillouin/ultrasonic literature; authors note it deviates systematically from the volume data vs. the unconstrained fit (sibling row). | ||||||||||||||

| Why this differs from similar rows: Alternative BM3-form fit constrained by external KS0 = 253 GPa (same constraint type as the Vinet-form alternative fit elsewhere in this paper); sibling row is the unconstrained fit. | ||||||||||||||
