Parameter set "pbc-0-3"

This set consists of mainly older Slater-Koster files with a focus on solid state systems [SiO,SiC]. The parameters might also be applicable for organic systems, but one usually would only expect a more qualitative accuracy. So use the "bio" set instead for bio molecules.

The silicon parameters are good for silicon clusters (using a sp basis only) [Silicon], while the same parameters with d-orbitals on Si are used for silica.

The fluorine parameters have been validated especially concerning the relative energetics of SiF_x and CF_x [Fluorine].

The iron parameters have been applied to structural and magnetic properties of iron clusters [Iron], but should also give reasonable results for bcc bulk iron.

This version is a bugfix version of the pbc-0-2 set, fixing a format incompatibility detected by recent DFTB+ releases. The change does not have any influence on the physical quantities calculated with the set.
