Production and propagation of secondary antideuteron in the Galaxy

Dear Editor and Referee

We greatly appreciate your valuable suggestions on our paper, which have helped to improve it. Your comments allowed us to clarify our conclusions and to include important works from other authors. A new version of the manuscript including changes that acknowledge the referee’s comments was prepared. We hope that this revised version is suitable for publication.

The authors.

1.- The following line was added in section 5 (Conclusions): "Previous calculations are consistent with this result [21, 22]", where references [21] and [22] are those suggested by the referee.

2.- In section 4.2: “... AMS-02 \bar{d} sensitivity [19] (green lines), considering the projection with a superconducting-magnet configuration.”

3.- In section 5.0: “A similar result is obtained when an AMS-02 sensitivity, with a permanent-magnet configuration for 11 years, is considered [20].”

4.- In section 5.0: “Interestingly, a recent AMS-02 sensitivity projection for 2030 with a planned detector upgrade is close to the maximum of our secondary \bar{d} flux estimation [20] (Fig. 2), suggesting that AMS-02 would be practically background-free for possible antideuteron observation coming from dark matter or new astrophysical production mechanisms.”
