We have also reviewed the effect of upper cut-off frequency, spin-magnitude, spin-orientation, mass-ratio and signal-to-noise-ratio on the posterior distribution of \delta \kappa_1 and \delta \kappa_2 (or \delta \kappa_s and \delta \kappa_a). We use simulated signals for this study which are modelled using IMRPhenomPv2 approximant. The results are as expected and are summarized [here](https://git.ligo.org/nv.krishnendu/lalsuite/-/wikis/Results-review#injections).

We highlight a couple of points which were outside the scope of the review, given the timeline for the exceptional events:

|
Noise systematics study for a population: We are satisfied with the code/pipeline for the purpose of analysis on a single event, like GW190814. However, for the purpose of combining results, as might be the case of the O3a TGR paper, we would also like to see results from a noise systematics study (and a corresponding pp-plot). This study is currently being undertaken: https://git.ligo.org/nv.krishnendu/lalsuite/-/wikis/Systematics-Studies

|
Waveform systematics study: This test also is implemented for the phenom family of waveforms, and we strongly encourage a test of the waveform systematics by considering injections with different approximants and recovering with the above pipeline.

Barring these two pending investigations, we are happy to sign off on the code for production of results for GW190814.
