Evidence from the paper
"the Birch-Murnaghan isotherm based on K0T = 152.3 GPa and K'0T = 4.92 derived from the ultrasonic data of the present study" (Fig. 4 caption); "The isothermal bulk modulus KT of 152.3 GPa derived from the value 154.9 GPa for KS via the well-known identity KT = KS(1 + αγT)^-1... yields (∂KT/∂P)T = 4.92."
