  We discuss and clarify a simple and accurate interpolation scheme for the
spin-resolved electron static structure factor (and corresponding pair
correlation function) of the 3D unpolarized homogeneous electron gas which,
along with some analytic properties of the spin-resolved pair-correlation
functions, we have just published. We compare our results with the very recent
spin-resolved scheme by Schmidt et al., and focus our attention on the
spin-resolved correlation energies and the high-density limit of the
correlation functions.
