Author comments upon resubmission

Dear Editor,
We thank the referee for their comments and suggestions. We address the referee’s points one-by-one and summarize the resulting changes we made to the manuscript.

Yours sincerely,
BLFQ Collaboration

List of changes

I. Page 2, after Eq. (2), end of the paragraph, we have included the following text:
The LFWFs are boost invariant in the longitudinal and the transverse directions. The BLFQ approach employs a suite of analytical and numerical techniques for setting up and solving the eigenvalue problem in a convenient basis space [3-5]. Complementary insights into nonperturbative QCD can be achieved from the discretized space-time euclidean lattice [6] and the Dyson-Schwinger equations of QCD [7].

II. Page 2, second last paragraph: We have modified text in the following form:
We find consistency between our results and the precise low Q^2 EMFF data. Meanwhile, notable deviations have been observed at large Q^2. Note that our choice of Nmax, implies the UV regulator ΛUV ∼ b\sqrt{Nmax} ≈ 1 GeV [4]. Thus, our predictions are most reliable in the low Q^2 region.

III. Figure 5 has been include, the corresponding discussion has been added last paragraph before conclusion.

IV. Conclusion and outlook section has been included.
