Why this differs from similar rows?
Cites K_S0=273 GPa from Mao and Hemley (personal communication, 1989), close to the adopted Knittle and Jeanloz value; sibling row cites a lower literature value (~245 GPa).

Evidence from the paper
the K_S0 value for perovskite in Table 1 [Knittle and Jeanloz, 1987] is close to the value of 273 GPa obtained by Mao and Hemley (personal communication, 1989)
