The joint probability distributions for the mass ratio q and effective inspiral spin χeff. The mass ratio is well constrained away from equal masses, q < 1. The signal’s effective inspiral spin is well measured to be ﹩{\chi }_{{\rm{eff}}}=-0.0{1}_{-0.07}^{+0.06}﹩ and is not strongly correlated with q.
