Evidence from the paper
'The authors derived V0 = 77.369(8) Å3, K0T = 159(1) GPa, K'0T = 3.8(1), Θ0 = 576 K, γ0 = 1.63(2), and q = 0.54(3) for HS (Mg0.64Fe0.36)O Fp' (van Westrenen et al. 2005).

caution
Present authors note these K0T and K'0T values should be considered with caution because of the Au scales used (Anderson et al. 1989; Shim et al. 2002).
