Why this differs from similar rows?
Table 1 column (e): parameters from the Kushwah EOS fit to seismic data; sibling row uses column (a), a different EOS formulation (modified Rydberg), giving a different K'.

note
Parameters are for the bulk lower mantle fitted to seismic (adiabatic) data along the geotherm, not a specific mineral phase; no V0 reported (density rho0 given instead). Paper contains no EOS parameters for bridgmanite, ferropericlase, post-perovskite, or CaSiO3 perovskite individually.
