Selected source properties of GW230529. The plot shows the one-dimensional (diagonal) and two-dimensional (off-diagonal) marginal posterior distributions for the primary mass m 1, the mass ratio q, and the spin component parallel to the orbital angular momentum ﹩{\chi }_{1,z}\equiv {{\boldsymbol{\chi }}}_{1}\cdot {\hat{L}}_{{\rm{N}}}﹩. The shaded regions denote the posterior probability, with the solid (dashed) curves marking the 50% and 90% credible regions for the posteriors determined using a high-spin (low-spin) prior on the secondary of χ 2 < 0.99 (χ 2 < 0.05). The vertical lines in the one-dimensional marginal posteriors mark the 90% credible intervals.
