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