The joint posterior probability density estimates for the magnitude and tilt angle of the spin vectors of the source, obtained using the four indicated waveform models at a reference frequency of fref = 20 Hz. The left and the right semicircles in each panel show the spins of the primary and secondary component objects, respectively. For all models, the spin vectors are constrained to have small magnitudes.
