Summary statistics derived from relative binning compress BNS gravitational wave data into O(1000) points, enabling efficient neural posterior estimation with well-calibrated posteriors validated against nested sampling on 1024 injections.
The clear exception here is the phase parameter, where the neural posterior fails to reproduce the wavy characteristics in thebilbyposterior
