Extended Data Fig. 4

a–f, Results are shown for tetragonal CaPv at 300 K (a, b) and cubic CaPv at 900 K (c, d) and 1,500 K (e, f) as a function of unit-cell volume of CaPv. The solid lines represent fits of the experimental data with the finite-strain EOS (equations (1)–(12)) and the shaded areas represent the 95% confidence intervals, calculated from the trade-off between KS0 and K′ (Extended Data Fig. 4a–e) and G0 and G′ (Extended Data Fig. 4b–f). Most of our experimental data agree within the 95% confidence intervals, demonstrating the small correlation coefficients between the fitted variables.
