Why this differs from similar rows:
Reports isothermal pressure derivative (dKS/dP)_T=4.90 from ultrasonic Cij(P) data, used with Birch-Murnaghan extrapolation; sibling row reports isentropic derivative instead.
Why this differs from similar rows:
Reports the isentropic pressure derivative (dKS/dP)_S = 4.84, derived from the isothermal value (4.90, sibling row) via a thermodynamic identity, used to construct the Hugoniot.
