Figure 4: Localization of two QDs with different post-selection criteria.

(a) Used all photon counts, (b) used a photon count rate threshold of the lowest 10% intensity periods and (c) used the single-emitter antibunched photon counts (as in Fig. 2c). All localizations use N=1,500 photons. For clarity of comparison, (a) contains a random selection of 200 data points. Scale bar, 50 nm.
