# Stealth/systematic biases in the compact binary parameter estimation due to spin induced moments.
# Stealth/systematic biases in the compact binary parameter estimation due to spin induced moments.
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.
