Why this differs from similar rows?
Table I, static GGA calculation using an effective core pseudopotential with large-core Mg; sibling rows use small-core Mg, PAW potentials, or a pressure-corrected fit.

Evidence from the paper
TABLE I. Static equation of state of MgO from different GGA calculations. ECP, Large-core Mg | 77.629 | 151.707 | 4.212. 'here we preferred the third-order Birch-Murnaghan EOS ... EOSFIT program was used for fitting EOSs, the parameters of which are listed in Table I.'
