Evidence from the paper

We then repeated this procedure for Mw84 by using the same equation of state except with a zero-pressure volume V0 = 9.79 ± 0.04 Å3/atom as reported by Wicks et al. [21]. Table 1: Mw84 Model — V0 9.79 ± 0.04, K0T 155.3 ± 2.2, K'0T 3.79 ± 0.11. Footnote b: Identical to Mw94 model except for V0 taken from Wicks et al. [21].
