3 Energies in OUTCAR

[rpnabar]

I think I understand the two energies in OUTCAR:

energy without entropy

AND

energy(sigma->0)

A reading of the manual and previous forum posts makes me think that the "energy(sigma->0)" is the correct energy to use for most purposes.(please correct me if I'm wrong!)

Additionally they should be close assuming I ran my calculation correctly and the "entropy T*S" term is small on a per atom basis.

But what is the third energy given by:
"free energy TOTEN ="

I'm thouroughly confused here!
