Orbitals in WAVECAR

Dear all,

I'm curious what kind of orbitals are written in WAVECAR files - are they PAW orbitals or true (unprojected) orbitals? I suspect that WAVECAR contains PAW orbitals (because we doing this type of calculations), but then I would be interested to know how to make vasp (4.6 e.g. or may be 5.2 - any of those) write true orbitals in WAVECAR. Just to explain, the orbitals I get from WAVECAR are not orthogonal (that is why I'm saying that they are most likely PAW orbitals), but I would like to deal with the orthogonal orbitals, which I call true.

Thank you!

The pseudopotentials used in VASP are not norm-conserving. The eigenstates are orthonormal with respect to an S matrix.
