But precision without accuracy is a problem. Systematic biases in waveform models, prior assumptions, and pipeline choices can lead to confident but wrong measurements.</p> <p>This paper gives a comprehensive assessment of how accurately next-generation detectors can measure neutron star radii, identifying and quantifying the dominant sources of systematic error. We show that achieving sub-percent accuracy on the radius, a key target for constraining the equation of state, requires careful control of waveform systematics and prior choices, and we give practical recommendations for the O5 era and beyond.</p> <p>Published in Physical Review D (2025)</p>
