Results of SEOBNRE and IMRPHENOMPV2 analysis of simulated data using GW190521-like injections. Left: posterior distributions for eccentricity at 10 Hz for GW190521-like injection studies with varying e₁₀ and ﹩{\chi }_{p}﹩, obtained using SEOBNRE. Right: posterior distribution for precession parameter ﹩{\chi }_{p}﹩ for GW190521-like injection studies with varying e₁₀ and ﹩{\chi }_{p}﹩, recovered using IMRPHENOMPV2. The prior distributions are shown in gray.
