Figures

Image of FIG. 1.
FIG. 1.

Three-state model (upper panel) and the corresponding two-level model (lower panel) of a single molecule. The dashed line in the upper panel separates the states in the three-state model that lead to the bright and dark states in the two-state model.

Image of FIG. 2.
FIG. 2.

Minimum, average, and maximum estimates of from arrival time trajectories as a function of the number of trajectory counts for low, medium, and high excitation intensities, , 16, and 64, as indicated. Upper panels show estimates from the intensity correlation function (ICF) and the lower panels from the histogram of interarrival time (HIT). The error bars indicate the standard deviation of the estimates. Note the logarithmic scales. Other simulation parameters: , .
