Hi Scott and Ross,

I have checked the PIMD tests and everything is fine. The differences
between the current and old results are due to a slightly different
value of the Boltzmann constant in constants.f. In the previous
versions KB was set to 8.31441d-3 / 4.184d0 while now
KB = ( BOLTZMANN * AVOGADRO) / JPKC.

The changes related to nscm do not affect PIMD.

So, I think we can keep the current tests as they are.

Thanks,
Francesco
