\label{fig:altern_hist_double} Histograms used for excitation the selection/determination of the  alternation periodsselection  for two typical smFRET smFRET-ALEX  experiments. Distributions of photons detected by the donor channels are in \textit{green}, and by the acceptor channel in \textit{red}.  The light \textit{green} and \textit{red} shaded areas mark the donor and acceptor period definitions.  (a) µs-ALEX alternation histogram, i.e. histogram of timestamps \textit{modulo} the alternation period for a smFRET sample.
