1 When plotting in POST, besides T (Kelvin), you can also use T_C or T_F to plot temperature in °C or °F.

2 Only for single-substitutional-lattice solution phases such as AQUEOUS solution and GASeous mixture phases and for interacting species on the substitutional sublattice of two-sublattice solution phases (such as the phases BCC_A2 and M6C phases).

3 In natural logarithm (lnAC=MU/RT)
