Frequentist detection of a simulated thin domain wall signal. The thin wall with strength \(h=0.10 \text{ ns}\) interacts with a network of 30 white noise clocks, each with \(\sigma =0.05 \text{ ns}\), at time \(t_{0}=0\). The common reference clock contribution is white noise with \(\sigma _{\times }= 0.006 \text{ ns}\). Bottom panel: simulated clock bias data for 6 of the 30 clocks with the injected signal included. For visual clarity, each data stream is shifted by a constant. Top panel: magnitude of the corresponding SNR statistic ρ for the same time scale
