[x] The authors have obtained masses that are 1-sigma larger than those reported by Grimm+ 2019, except for one planet and claim that the difference is the amount of data analyzed. Have the authors done their analysis only with the time period of data that Grimm+ used to verify that indeed this is the source of the discrepancy? Please share this comparison. Although 1-sigma values are considered within modeling efforts, the effect on the inference in composition is dramatic. Thus, it is essential to understand the origin of any discrepancy.
[x] The authors have used their N-body code but also GENGA to check their results and to check for stability. Why was this work not carried out with GENGA for all the analysis? what are the advantages of their N-body code?
Simon Grimm - could you help with these?
