Importance of the initial conditions for the standard fitting method for three distinct total numbers of photons: 200 (in light gray), 1000 (in dark gray) and 100000 (in black). LerayAymeric Padilla-ParraSergi RoulJulien HéliotLaurent TramierMarc 2013 <p>We have considered three fractions of interacting donor <i>f<sub>D</sub></i>: 0.25 (A), 0.5 (B) and 0.75 (C). The minimal fractions of interacting donor are plotted in the left part and the lifetimes of the donor in presence of the acceptor in the right part. For each condition, the dotted lines represent the simulated values and the markers with error bars represent the medians and interquartile ranges of 4096 simulated TCSPC histograms (with <i>τ<sub>F</sub></i> = 1.5 ns, <i>τ<sub>D</sub></i> = 2.5 ns and <i>N<sub>ch</sub></i> = 64 channels).</p>
