Dear Roozbeh,

> extracted_H0.jpg please compare the above results with the following 
> Porezag, D., Frauenheim, T., Köhler, T., Seifert, G., & Kaschner, 
> R.(1995).Construction of tight-binding-like potentials on the basis
> of density-functional theory: Application to carbon. Physical Review
> B, 51(19), 12947.   Cited by 1966

I did not look up the publication, but I am pretty sure, it uses
original potential superposition scheme, while the sets you mentioned
were created with density superposition (taking the non-linearity of the
xc-functional into account). The values, therefore, can differ.

  Best regards,

  Bálint
