Why this differs from similar rows?
V0 adjusted to 160.452 A3 to match isobars of runs 3A, 3B, and 8 of Wang et al. [1994]; K0 and K0' held identical to sibling row 546's adopted values.

Evidence from the paper
'If we adopt V0=160.452 Å3 assuming K0, K0', and Θ0 to be the same as the present ones, the calculated isobars are in good agreement with those of runs 3A, 3B, and 8 as shown by the broken lines in Figure 1. This value of V0 is 0.18% smaller than the theoretical value by Stixrude and Cohen [1993].'
