Query: Filtering a distribution simultaneously in real and Fourier space   We present a method to filter a distribution so that it is confined within a
sphere of given radius r_c and, simultaneously, whose Fourier transform is
optimally confined within a sphere of radius k_c. Our procedure may have
several applications in the field of electronic structure methods, like the
generation of optimized pseudopotentials and localized pseudocore charge
distributions. As an example, we describe a particular application within the
SIESTA method for density functional calculations, in removing the spurious
rippling of the energy surface generated by the integrations in a real space
grid.
