FIG. 16

Contours of constant photon number as labeled on the figure that give Inline graphic(𝕊, 𝕆) equivalent to 95% likelihood of distinguishing two states at FRET distances of R1/R0 and (R1 + δR)/R0. The left panel shows the contribution from donor photons, the center panel shows the contribution from acceptor photons, and the right panel shows contributions from both. Experimental parameters are the same as in Fig. 15
