All LDA atom file (pseudopotential and associated basis sets) are developed by Peter A. Schultz (Sandia),
P.A. Schultz, unpublished.
All LDA potentials are Hamann type norm-conserving pseudopotentials,

except for N,C,O,F,Ni,Cu,Zn, and Ga(d10) which use the Troullier/Martins type,
N. Troullier and J.L. Martins, Phys. Rev. B 43, 1993 (1991),
Also, alkali atoms, alkaline earths, and several early transition metals atoms and early main group atoms incorporate the partial core correction:
