Evidence from the paper
TABLE 1. Input parameters used in the present study: Lower mantle K0 = 206.06[1], K0' = 4.2[1], K_inf' = 2.41[1], k = 3.153. 'K0' is the first pressure derivative of isothermal bulk modulus (KT) at zero pressure'. Values cited from Stacey and Davis [1].

note
Bulk lower-mantle region parameters, not a specific mineral phase (bridgmanite/ferropericlase/etc.). No V0 reported; only volume ratios V/V0 tabulated. Outer core row (K0 = 124.553 GPa, K0' = 4.9599, K_inf' = 3.0, k = 3.095) omitted as not a lower-mantle phase.
