 %To conclude this section, we point out that, thanks to the definitions \eqref{eq:def_weebasis} and \eqref{eq:mu_of_r} as well as the properties \eqref{eq:lim_W} and \eqref{eq:large_mu_ecmd}, independently of the DFT functional, the present basis-set correction
 %i) can be applied to any WFT method that provides an energy and a density, 
 %ii) does not correct one-electron systems, and
 %iii) vanishes in the CBS limit, hence guaranteeing an unaltered CBS limit for a given WFT method.
