Reviewer 1 Report

Comments and Suggestions for Authors

As the part II of Gauge-invariant perturbation theory on the Schwarzschild background spacetime, in this manuscipt, the author introduce the gauge invariant perturbation of even parity under the Schwarzschild space time. The logic and the calculation seems correct in this manuscrpt. I have the following two question to ask: 

1) Can the author show some examples of this paper and the Regge-Wheeler gauge?

2)As we know, the gravitational wave only have two propagating modes. Can the analysis in this paper show this point?

If the author can answer this two question appropriate, I will recommend this manuscript to publish in Universe.
