The s and p tight-binding parameters were fit to first-principles Linearized Augmented Plane Wave (LAPW) results. The d orbitals were excluded from the fit. The following ranges were used:
| Structure | Minimum Range Lattice Constant (Bohr) | Maximum Range Lattice Constant (Bohr) |
| fcc (A1) | 8.40 | 9.20 |
| bcc (A2) | 6.60 | 7.40 |
| simple cubic (Ah) | 5.20 | 6.00 |
| Reference | Phys. Rev. B 57, R2013-6 (1998) | |
Use of the parameters outside of these ranges may result in unphysical behavior.
