\alert{For clarity, we now mention that the expression in Eq. (41)
has a general structure, which should be exact for any uniform system. We
point out that, unlike in the exact theory, the correlation components
of eLDA are weight-independent. We
also mention explicitly that these components will be constructed (in
the following) from
the correlation excitation energies of a finite uniform electron gas. We
refer to Sec. III for further details.}

{Page 4: It would be helpful to note clearly near eqn 40 that the authors' focus on LDA correlation differs from what many readers will be used to in ground-state LDA, namely using LDA exchange as well, instead of combining it with HF Hartree-exchange as is done here.

We have added a note to clarify this point just below Eq.~(40).}
We have added a note to clarify this point just after Eq.~(41).}
