Reviewer 1 Report
The paper studies the parameter optimisation for the space based DECIGO, aiming to observe primordial GWs. It optimises the SNR considering thermal noise and quantum noise as the noise sources and signal above typical cutoff frequency of GWs from double white dwarfts. The method is adequately described and results are clearly presented. I recommend the paper for publication after the authors consider below minor comments,
- It would be better if the authors can state the outcomes more specifically in the abstract.
- In Equation 2, the speed "v" is not defined.
- Below line 118, in the sentence "In our simulation,...", is the "except" a proper word here, or the authors want to say "when R is very large".
- In line 236, should it be Figure 3(b) and (d)?
- In Figure 6, the two captions are the same.
- In line 249, "The increase of...". Is there constrain for this statement? I suspect this is true.
- In Figure A2, the start radius is 0.5m, while in above optimisations, the start radius is 0m. It is better to keep consistent.
- In terms of the results, when R=1m, will further optimising the thickness give better SNR. If Yes, what is the reason this is not considered? It is better to discuss the possibilities beyond the two models chosen in this paper.
- I suggest to add some discussions on the mirror mass and radius limit.
