(a) Loci of strong minima of (
) and weak minima (
in the inset) along isobars for αP. (b) Loci of strong minima (
) and weak extrema (
and 
in the inset) along isotherms. (c) Projection of αP extrema in T − P plane. Orange lines are the loci of weaker extrema 
and 
. The large circle with A identifies the region where the divergent minimum in αP is observed. Symbols not explained here are as in Fig. 2.
