Performance of the non-fitting methods (polar approach in black, moments method in blue and mfD in red) as a function of the number of temporal channels for N = 200 photons acquired with time gated system.

Three fractions of interacting donor fD are considered: 0.25 (A), 0.5 (B) and 0.75 (C). We have indicated the fraction of interacting donor and the mfD in the left part; the donor lifetime in presence of the acceptor τF and the mean lifetime <τ> are in the right part. In all graphs, the dotted lines represent the simulated values and the markers with error bars represent the corresponding medians and interquartile ranges of 4096 simulated histograms whose parameters are: τF = 1.5 ns and τD = 2.5 ns.
