From: Loophole-free Bell test using electron spins in diamond: second experiment and additional analysis
CHSH parameter S, number of Bell trials n and post-selected complete-analysis local P-value versus window start offset for the event-ready photon detections at location C, for the first (grey) and second (orange) dataset.
The time-offset shown is with respect to the predefined windows (corresponding to the dotted line). Confidence region shown is one sigma, calculated according to the conventional analysis. Shifting the window back in time, the relative fraction of heralding events caused by photo-detection from laser reflections increases, thereby reducing the observed Bell violation.
