is the bare Thomas-Fermi kinetic energy. If we assume T [ρ] = T s [ρ] then T corr [ρ] is called the Pauli kinetic energy. The modulating function F(r) is also known as enhancement factor if we consider the Kohn-Sham limit of kinetic energy. Deb et. al. proposed a parametric model of F(r) for closed shell atoms as a sum of a few Gaussian functions. Following several compelling evidences , they computed F(r) from Hartree-Fock kinetic energy density
