[DFTB-Plus-User] LDA or GGA-PBE for mio-0-1 trans3d znorg-0-1 for atomic spin constants ?

[Markus Kaukonen]

Dear DFTB,
I use mio-0-1 (http://www.dftb.org/parameters/download/mio/mio01/)
and its extensions
trans3d-0-1 (http://www.dftb.org/parameters/download/trans3d/trans3d01/)
znorg-0-1 (http://www.dftb.org/parameters/download/znorg/znorg01/)

Question:
Which Atomic spin constants (appendix D in DFTB+ manual)
should I use for different atom types?
Is it LDA for H C N O
and
GGA-PBE for metals and S?
What about Si ?

I got this impression when reading the references
