Evidence from the paper
The volume (V0), the bulk modulus (B0), and its pressure derivative (B0') at ambient pressure were estimated by a least-square fit of calculated V-E curves to the integrated form of the third-order Birch-Murnaghan's equation of state.

note
Only the cubic lattice constant a is tabulated, not V0; Table II (this work) also gives aggregate B = 164 GPa from elastic constants at zero pressure.
