Currently, the reference state is fixed.
To change the reference state, one has to change the helmholtzCoefficients.idealPower.
Examples.Validation.ReferenceState contains some more explanation

don't forget to decrease the helmholtzCoefficients.idealLog by 1 when switching from CPP to PH0
(compare e.g. Butane.fld, it has both CPP and PH0)

and possibly divide by -T_c, as done e.g. here:

When changing the reference state, SMIN, SMAX, HMIN, HMAX, SCRIT and HCRIT have to be adapted, too.
