% dt     =     Time width of one TCSPC channel (in nanoseconds)
% tau     =     Initial guess times
% init    =    Whether to use a initial guess routine or not
%
% The return parameters are:
% c    =    Color Shift (time shift of the IRF with respect to the fluorescence curve)
% offset    =    Offset
% A        =   Amplitudes of the different decay components
% tau    =    Decay times of the different decay components

% zz        Fitted fluorecence component curves
% t     =   time axis
