of among the 250 simulated sources for spin priors of $\chi_{1,~2} \leq \{1, 0.7, 0.4, 0\}$. $\chi_{1,~2}<1$ and $\chi_{1,~2}=0$ correspond to the spinning and non-spinning analyses

From these PDFs, it is clear that \emph{very} strong prior assumptions are required to have measurable effects on mass estimates. Assuming NSs to be spinning with $\chi_{1,~2}\leq 0.4$ a priori only constrains masses by an extra few percent compared to allowing them to have $\chi_{1,~2} \leq 1$.
