| 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). | ||||||||||||||

| Why this differs from similar rows: Cites lower K_S0~245 GPa from Kudoh et al. and Yeganeh-Haeri et al.; text says results are nearly identical if K_S0' is instead raised to ~4.5 (a proposed adjustment, not fitted). | ||||||||||||||
