This page is for a top-level management of all the ongoing activities. Avoid adding low-level details which can be added as additional pages linked from here. At present, we think of three follow-up studies to be concluded in the next three months. The broader idea and the milestones are given in this page. Milestones are marked :white_check_mark: once achieved. The plans are below

* Using simple combining, produce the no. of events v/s bounds on Ks plot for up to 1000 events. This is done by assuming that the population of 1000 events is made by repeatation of 10 O1-O2 events with suitable SNR scaling such that they follow 1/rho^4 distribution (Saleem).

### Idea
|
|
To assess how the presence of a non-BH compact object with spin-induced deformations can bias the inferences of binary parameters such as masses, spins and distances. Preliminary studies are done and found that the spin inference is most affected by ignoring the non-unity value of kappa parameter. Apart from reporting how different parameters get affected, it might be worth also exploring how the formation scenarios inferences (based on effective spin distribution) can also get biased.
