One crucial step in the formation energy estimation is the determination of an alignment constant which is determined by comparing the local potential profiles of the defective and pristine supercells. <a href="https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.102.016402" rel="nofollow" target="_blank" data-saferedirecturl="https://www.google.com/url?hl=zh-CN&q=https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.102.016402&source=gmail&ust=1622020485632000&usg=AFQjCNG_6i7ecR7Gu8fxWpyZY5diyfqbAw">https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.102.016402</a> (Fig. 2)</div><div><br></div><div>My question is, for the local potential profiles is V_HARTREE_CUBE sufficient?

However, I find that the Hartree potential profile of the defective supercell varies a lot from that of the pristine supercell and contains a lot of oscilattions mainly around the defect due to the relaxation of atomic positions, which would potentially make the alignment procedure impractical.
